The OpenStealth Project: Visual Stealth for The Masses!

reply to post by StargateSG7


----

One more December update as to the progress of the OpenStealth Project regarding
the latest progress on the use of GLASS MASTERS to imprint optical waveguides
onto BOTH flexible membrane materials (i.e. clothing) and hard plastic panels.

1) Issue #1 is the actually process of etching an optical
waveguide pattern onto a THERMALLY STABLE GLASS SUBSTRATE
using a number of different processes. Light Path Construction Software
has been a GREAT HELP in actually choosing final materials and constructing
the blueprints for the actual optical waveguide placement and routing such
that light travel distances are the same on all input/output
sides and that the modeling of incoming light reflectance,
refraction and diffraction issues are resolved.

On an actual construction basis, the current means and methods
used to press waveguides onto various hard and soft substances
has allowed us to virtually model MULTIPLE performance parameters
such that we NOW KNOW what specific technical hurdles need to
be overcome during the actual manufacturing process.

Wave Guide glass masters MUST be thermally stable and mechanically inflexible
so that final wave guide edges LINE UP PRECISELY when stamped hard-plastic
waveguide panels are glued/fused together so that the multi-frequency
light that is "ingested" into the waveguide path does not scatter at
the optical-tunnel edges/seams thus reducing or otherwise changing
the light output at the output end of the waveguide which forms
the better part of this PASSIVE optical stealth system.

2) Since I'm thinking INEXPENSIVE, there is an abstract of a paper
presented in 2005 which IS of assistance in creating the microlens
arrays used for the input and output of light waves into a PLASTIC
waveguide using etched glass masters. One key issue NOT discussed
though are the ANTI-REFLECTIVE coatings that NEED to be vapour-deposited
onto the lens arrays to assist in the preservation of the input state of
the multi-frequency light wave as it bounces off of the internal walls
of a waveguide and exits on the other side of an optical-stealth covered object.

Particular issues that arise are the properties of an anti-reflective
lens coating that allows a specified angular distance/swath of incoming
light to be gathered into the stealth panel and REJECTING light coming
in from all other angles outside of the specified angular distance.
Microlenses must be kept a specific distance apart (MINIMUM half-the
diameter of the microlens) from each other and the angular input from
the front/crown of the micro-lens SHOULD BE on a -45 Degree to +45 Degree
from the centre-point of the lens for OPTIMUM stealth and to PREVENT light
reflected off of the surface of an ADJACENT microlens being gathered for
input into the current (i.e. WRONG!) waveguide path.

Anti-reflective lens coatings MUST also take into account
the ANGLE OF INCIDENCE when a particular TYPE of coating
is being applied to the input/exit lens arrays on optical
stealth waveguides:

Microlens fabrication using an etched glass master

P. Zhang, G. Londe, J. Sung,
E. Johnson, M. Lee, H. J. Cho

Abstract

This paper presents a micromachining technique to fabricate microlenses
using an etched glass master. The isotropic etching profile of the
glass master was utilized for microlens replication. The master was
treated by C4F8 plasma to form a conformal anti-adhesion layer.
Lens arrays were replicated on polymer substrates by hot embossing.
Microlenses with a large numerical aperture could be fabricated
with this method. This work facilitates and simplifies fabrication
steps for microlenses.

3) The basics of ETCHING waveguides comes from the CD/DVD disc manufacturing
industry which is as outlined below:

Overview of the CD/DVD mastering of Glass Masters:
en.wikipedia.org...

Detailed Process Overview:
www.wizbit.net...

Video Overview:
www.youtube.com...


In our case, we are using an ablative laser process to etch an ENTIRE multi-beam
light path array onto two large 12" by 12" thermally STABLE and mechanically inflexible
glass panels which are then used to stamp those wave-guides onto two plastic panel
substrates which are each metallized with an optically reflective surface
ON ONLY the waveguide impressions. This is done though a charged vapour
deposition process.

Since we MUST PERFECTLY ALIGN and glue together two halves of a 180 degree
stamped circular waveguide panel impression together to form a 360-degree
"Optical Tunnel", the precision required for the alignment of the two
waveguide panels is immense. While the waveguide tunnels can be as large
a diameter a 0.2 millimetres to 0.5 millimetres to allow multi-frequency
light input/output, there is a DEFINITE technical issue with regards to
upper-lower panel waveguide impression alignment on a mechanically
consistent basis.

The seam that is created at the two-panel layer boundaries DOES HAVE
a scattering affect on light waves internally reflecting within the
walls of the waveguides but no SPECIFIC chroma (colour) shift or
Luminance (brightness) shift has yet been studied or measured with
a computerized light wave sampling system. Basic visual testing has not
yet encountered daytime human-eye visible colour fringing or blurring effects.

Both Optical-based and Infrared night vision testing of the optical
stealth panels ARE CURRENTLY FORESEEN to have a small positive sighting
on the EDGES of an optical-stealth panel covered object. (i.e. mild
blurring or fringing on object edges). The MILD nature of the edge
fringing may be acceptable due to high night vision operator
task loading who will LIKELY MISS such fringing
during active night-time operations.

Infrared emissions detection can be minimized by using 0.5mm
and larger diameter optical tunnels AND by using thermally
transmissive materials for the input/output micro lens arrays
and thermally reflective walls for the interior waveguide paths.


4) Using Hard plastic panels HAS NOT been a great technical hurdle
to overcome when using glass masters to stamp a pre-defined array of
optical waveguides onto semi-rigid plastic panels. This BODES WELL
for actual COST-EFFICIENT manufacturing at a price range less than
$5.00 per 12" by 12" panel at low-volume runs when allowing for the
manufacturing of box-like structures that have optical waveguides
that traverse around the corners and edges of a box-like structure
to the opposite side. At high volumes of 25,000 panels per run,
manufacturing costs can be as low as $2.00 U.S. per
stamped and aligned/glued two-layer 12" x 12" square
plastic optical stealth panel. Manufacturing runs in
excess of one million panels would see a dramatic
reduction to just over material and machine costs
possibly even down to less than $1.00 per panel!

Part 2 - continued from above:


WHAT HAS BEEN A GREAT ISSUE is applying the same glass stamped
manufacturing technology to flexible MEMBRANES (i.e. rubber-like
clothing material) which not only flexes, but also has a VARIABLE
rate of expansion and contraction which is a great barrier to the
use of the TWO-LAYER panel approach in creating optical waveguides
within stealth-clothing applications. The 180-degree two halves
of a membrane that would form an "optical tunnel" would NEVER
properly STAY aligned and thus the light waves would NOT properly
internally reflect within the waveguide to exit the opposite side
which is required in order to form an optical stealth material.

5) A novel tri-layer approach for flexible membrane optical stealth
is CURRENTLY BEING DISCUSSED and will be revealed here soon.

A technique used in lost-wax casting will be applied to microsized
optical waveguide manufacturing of FLEXIBLE optical stealth membranes
but this is CURRENTLY in the Research Phase and thus requires further
work before release on these ATS postings. Our VERY PRELIMINARY FINDINGS
are promising though on a SMALL SCALE (i.e. 1 inch by 1 inch).

So keep reading for more news!

IMO, I really want to see some LEGITIMATE examples of this technology before I even come close to buying into its authenticity. The below picture was stated to be a "media example" displaying the technologies capabilities, but the actual technology had to remain hidden:



I like to call this BAD photoshopping, not stealth.

"Open stealth" ???
Kind of an oxymoron.

Kind of like jumbo shrimp or publicly known secret.

Sorry, but our projects should be kept under wraps.
FedBizzOpps has made a lot of our research and projects a little too transparent.

If it"s open to the public...how could we ever have an advantage to another country's tech?

I hope that you're not in a position to make this happen.
Geesh.

OP should really make a promotional message with Billy Mays voice...

As interesting as this is, and as much as I'd certainly love to see OSP success, I'm awaiting some proof of concept video similar the Japanese Cloak of Invisibility concept:

That, of course, isn't true naked-eye optical 'invisibility', and is dependent on observing the effect through specialized equipment.

When will we have some proof of concept video demonstrating effectiveness of stealth range against not-static backgrounds for naked-eye optical, and other EM ranges?
Such wouldn't necessarily need be a full cloak similar the Japanese concept video. I small arrangement of panels demonstrating concept in a dynamic environment would certainly peak interest and illustrate levels of fidelity effectiveness.

Thanks.

P-M-H
So you, Stargate are the actual creator of this openstealth?

he is not.
there are tons of his posts on ATS, each single one making claims how knowledgeable he is, how many years he spent programming, developing and researching stuff, how many years he worked with government and so on.

and each single one of them is a LIE. i've already proven in one thread that he knows absolutely nothing about the stuff he's posting about, it's just a mix of technical mumbo-jumbo and BS to make him look smart so he can have a laugh while people believe him. he actually admitted that.

this extreme troll should be banned for life from ATS. nothing to see here, it's a waste of time.

PRE-AMBLE TO OPTICAL STEALTH SUBJECT MATTER:

Dear Jedi Hamster,

My Credibility is IRRELEVANT!

Because I actually HAVE NONE!

or to use an analogy....

The Moon is Made of Blue Cheese --- TRUE or FALSE?

Can YOU prove it EITHER WAY .... What YOU and I SAY proves NOTHING to others!

So your credibility argument is a non-sequitur (Latin for does not follow...) in the
context of ATS for you have NO ABSOLUTE PROOF that I am nothing more than
a 45 year old mother of three or a 20 year old arts student in New York having
fun at YOUR EXPENSE!

...or that in reality I'm a Senior Engineer in Toronto letting you have your fun
MAKING YOU THINK i now nothing about programming, when in reality I've designed
some of the most sophisticated Digital Signal Processing chips
and 128-bit successors to the Intel i7 ever created!

...OR...in reality, I've been a warehouse worker at the
same company for over 20 years and all I do every day is
ship XXX VHS tapes to over 40 different 3rd world countries
from a warehouse in East Vancouver and raise hackles on ATS
in my spare time!

YOU JUST DON'T KNOW --- DO YOU ?!

As you have so professed...it's all mumbo jumbo to you isn't?

Then please do make a WILD claim yourself and get someone
on ATS to refute and see where it gets you...NOWHERE! RIGHT?

This is ATS...!!! Above Top Secret !!!!! A Website of CONSPIRACY!

For all we know Simon Gray (ATS originator) and
Jim Marrs (Conspiracy Author) really ARE agents
of the NSA and started all this to keep better tabs
on whistleblowers and secret project leakers...AND
I AM PAID by the POWERS THAT BE to continue in a vein
of raising MUCH MORE Fear Uncertainty and Doubt (FUD)
(which I'm pretty GOOD AT DOING by the way!) to further
scare the willies out of all ye gullible sheeple which
I so despise...!!!!!!!!!

So again, let the my words fall where they...I may KNOW NOTHING...
I may KNOW SOMETHING....I MAY KNOW EVERYTHING...but once thing
absolutely IS FOR CERTAIN.....I'm a pretty darn good story teller !!!!!!

BACK TO THE OpenStealth Project SUBJECT MATTER AT HAND!!!!

Anyways the first demo video is a simple Chroma Key probably
done in Adobe After Effects or even Adobe Premiere by that
Maple Ridge, British Columbia, Canada based optical
stealth system manufacturer HyperStealth:

See link:
www.hyperstealth.com...

which demonstrates the DESIRED EFFECT of the real material.

The panels are created LIKELY using Negative Refractive Index
meta-materials which are PROBABLY nothing more that poly-plastic
(i.e. similar to Rhino-Liner) imprinted with optical waveguides
that reroute light waves though a pathway to the opposite side.

In reality, light is a finicky thig and YOU WILL get blurring
and fringing which would be visible on night vision goggles
of even decent general video cameras as blurring or fringing
on edges!

In my humble opinion, the ONLY WAY to get PERFECT optical stealth
would be to create a HUGE LOCAL-ONLY gravity field and let light
BE BENT AROUND the enclosed object (i.e. much like gravitational lensing)

See Link:
en.wikipedia.org...

there might be localized distortion of the background
but on small object I doubt people would notice too much!

BUT IN THIS CASE Hyperstealth's use of Negative Refractive Index
meta-materials WILL have Chromatic and Luminance artifacts:

Chromatic Aberration:
en.wikipedia.org...

and

colour shifting:

Abney Effect:
en.wikipedia.org...

and finally

the Purkinje Effect
en.wikipedia.org...

I HIGHLY DOUBT the Hyperstealth videos/photos
TRULY REPRESENT the OPTICAL STEALTH REALITY
are are more for marketing purposes.

However, DARPA (Defence Advanced Research Projects Agency)
DOES NOT NEED true optical stealth...just GOOD ENOUGH stealth
which is why they are looking into this company!

---

The LOWER video is of a researcher using a CAMERA to project
the background upon a reflective WEARABLE COAT to give the
ILLUSION of optical stealth...change the angle of view
and the effect goes away!

---

I personally think I have a better way that is A HECK OF A LOT CHEAPER!!!!

BUT it IS NOT PROVEN until that first optical panel is OFF THE PRESS
and IN USE...which won't be for a while yet!!!!! RIGHT NOW it's all
just Autocad drawing and a bunch of raytraced optical light-path
simulations!!!!!!

---

P.S. ALL CAPS MAKES ME GOOD AT YELLING !!! Even when I DON'T NEED TO YELL!!!!!

Sooo again ALL CAPS has ELECTROLYTES!!!!!! Which are GOOD FER YA!!!!!

Right now the OpenStealth Project is a large 3D array of data records
containing multiple 128 bit fixed point numbers which represent entry-points,
light-paths and exit points of 1000's of same-length waveguides pressed into
a simulated metallized polycarbonate plastic which detail the ray-traced
internal reflective pathways of multi-frequency light.

It is also an Autocad-style simulation of a PROPOSED manufacturing process
which would allow the use of glass-master stamps to CHEAPLY mass produce
and align "Optical Stealth Panels" to a level that POSSIBLY, MIGHT, MAYBE get
the price down to as cheap as $1.00 U.S. per panel at high production runs.

NOTHING is set in stone yet and only ONE tiny 1" by 1" TEST panel
has been HAND-MADE....!!!!

HOW TO UTTERLY DEFEAT OPTICAL STEALTH:

using nothing more than
Bread Flour and Paintballs!

Step 1: Takes sacks of bread flour and stuff a few cubic centimetres
into easily-shattering paintball-like spheres
approximate 1 to 2 inches in diameter.

Step 2: Take compressed air-gun and shoot said flour-filled spheres
BY THE TENS OF THOUSANDS into SUSPECTED optically-stealthed
enemy territory.

Step 3: Take Infra-Red and Optical Night Vision gear and WATCH CLOSELY
for splotches of WIDELY DIVERGENT stationary or moving temperature
differences that resemble the impact patterns of an exploded
flour-bomb round.

Step 4: Shoot Back At or Bomb the moving or stationary flour-bombed splotches!

THAT'S ALL FOLKS !!! Flour Bombs! That's ALL YOU NEED to defeat
Optical Stealth Panels that use ANY type of negative refractive
index meta-materials or imprinted optical waveguides.

AND for even better effect, highly aerosolized flour dust
makes for a VERY BIG BOOM! Throw a big spark into the air
and see what happens to the optically-stealthed object's
heat signatures when the air/flour mixture ignites!

a reply to: StargateSG7


Okie Dokie! Iit's April 17, 2014 and y'all been
wondering what I have been doing these
past few months on the OpenStealth Project.

I've been doing fine thank you very much!

Whilst a bit busy finishing off some actual
day-job programming and video production work
which actually allows me to pay my bills, I've been
figuring out ways to actually MANUFACTURE
a viable Optical Stealth Panel which is
basically a pressed waveguide created via
a fancy type of Autocad-like program imprinted
onto hard plastic.

As an update, there is a significant issue
with aligning two halves of a glass-stamped
panel such that the wave-guides ranging in
diameter from 0.2 mm to 0.5mm will form a
perfect optical waveguide and that the SEAMS
which DO form during the gluing process do not
cause multi-dB losses of light-output or even
prevent the bouncing of light within an
"optical tunnel".

Since we are trying the emulate what
fibre-optic cables currently do but
using pressed plastic panels, the
ALIGNMENT and covering up of the
seam is a big issue.

The problem is Illustrated below:

This is beyond impressive, myself and many others truly appreciate the work you are doing my friend . With these capabilities in the hands of so few, it's quite uplifting to see you using them for a cause such as this. Again, thank you.

a reply to: SolarZen

See these photo links as to how the system works:

It's quite a bit different than the technique that the Quantum Stealth of Maple Ridge BC Canada
uses (i.e. negative refractive index meta-materials funded by DARPA)...BUT...mine's a LOT CHEAPER
to make...


Links to how it all works:

a reply to: StargateSG7

In terms of cost, it's a matter of using modern printing technology to PROPERLY ALIGN
the two halves of a stamped micro lens and optical waveguide sheet so that a proper
cross-sectionally circular waveguide is produced. The interior seam that is produced
when gluing the sheets together is covered up using THIN-FILM Vapour Deposition
technology that is pressure-infused through the edges of each sheet.

You can PREVENT the undersides of the top-sheet micro-lenses from receiving
any vapour deposition in order to keep them optically clear by applying an electrical
charge to those microlens undersides ONLY which prevents the aluminum from
sticking. The sidewalls and seams having the opposite charge WILL receive the
aluminum vapour deposition so as to form a internally optically reflective surface
which will guide the incoming and outgoing light rays to their opposite side.

And since there is limited interference due to the multi-frequency nature of
daylight and nighttime the wave-guide work BOTH WAYS! AND...you can
coat the microlenses to prevent external reflection (i.e. Magnesium fluoride,
indium tin oxide or even DLC (Diamond Like Carbon for Infrared/Microwave stealth)

The diameter of the wave guides is determined by what frequencies of LIGHT you
which to guide. minimum 380 nanometres to 740 nanometres will do it
but I suggest you START AT 0.2 millimetres and GO UP TO 1.2 mm if you
want INFRARED and RADAR stealth too.

---

So until NEXT TIME....read away...

and for you Quantum Stealth/DARPA people good luck in keeping it
INEXPENSIVE to make like my method!!!!

a reply to: StargateSG7

While the above diagrams are a bit of a gross simplification
of the process of creating rigid optical waveguides, I have
noted some colleagues and friends who have expressed concerns
and have issues with the TOTAL NUMBER of optical waveguides
required in order to support an ingest/emmissive array of
microlenses and their associated pathways within a single
optical stealth panel.

My basic answer to the above issues is that a rigid optical
stealth panel CAN be created by stamping optical waveguides
into MULTIPLE LAYERS that are then glued together to form
a thick rigid panel that can support a density of up to
four micro-lenses per square millimetre where each waveguide
has a diameter of about 0.45 to 0.50 millimetres.

Such a diameter would be more than enough to support
the ingest and emmission of multi-frequency light with
wavelengths from 380 to 740 nanometres and INCLUDING
infrared wavelengths when Quartz microlenses
(which will pass through infrared radiation) are used.

As the OpenStealth Project is DESIGNED for creating
Optical Stealth Panels at an INEXPENSIVE price point,
I must be aware of and take into account that the
alignment technology when gluing multiple layers
of stamped optical pathways is based upon current
PRINTING PRESS ALIGNMENT technology which is only
good down to about 0.10 mm of offset from another
layer along each X and Y axis.

This offset error is another reason one has to
infuse the walls of the waveguides with a thin
layer of reflective surface (i.e. pressurized
thin film aluminum vapour deposition) so as to
FILL-IN the seams that are created between layers
of optical waveguides thus creating a SMOOTH
WALLED circular light-path that performs
the exact same function as a fibre-optic cable.

From a lay person's point of view one might
think this rigid panel would be VERY THICK
possibly up to 5 or 10 centimetres thick.

NO! There are methods to orient optical waveguide
pathways using compound curve patterns such that
at areal densities of 4 micro-lenses and pathways
per square millimetre it is POSSIBLE to get total
panel thickness down to 10 or so layers of optical
waveguide pathways and multi-panel pass-through
lightpaths such that we can assign a single-layer
thickness of 1.5 mm per layer for a total optical
stealth panel thickness of about 15 millimetres.

It is ALSO possible to LIMIT the areal density of
micro-lenses and optical pathways to one per square
millimetre or even less so that we can incorporate
stealthing into the MICROWAVE FREQUENCIES at 1mm+
wavelengths.

I have done NO CURRENT MODELLING of a lower-density
array of micro-lenses and optical pathways BUT this
is one avenue I will be exploring to reduce costs
and enhance manufacturability even further.

The biggest issue I have found is that the connections
of optical wavegudies between one panel to the next
MUST be taken into account and that a FLEXIBLE
edge-to-edge connection system be created so
that light refraction can be used on an
advantageous basis to connect one panel
to the next for passing the incoming
light through to another panel on the
OTHER SIDE of the object or person
which to be hidden from direct view.

In the next few days I will outline
a proposed edge-to-edge panel connection
system that will allow light panels to
flex and wrap around an object using
micro-lens based BALL-AND-SOCKET joint
system that changes the angle-of-incidence
between panels to allow pass-through
of light that originates from OTHER
panels. The point I am trying to make
is THAT NOT ONLY is the current panel
supporting the ingestion of incoming
light from it's surface array of
micro-lenses, but the current panel
is ALSO supporting the pass-through of
light coming from OTHER panels. The number
of layers you use MUST reflect the total
number of panels you intend to use to
wrap around a specifically-sized object.
This means you will have a final optical
stealth panel that is thick enough to
support the number of optical waveguides
that come from its surface AND still be
able to support the number of light-paths
coming from all PREVIOUS panels which are
organized from the FRONT of an object and
wrapping around to the BACK of an object.

THAT IS A LOT OF WAVEGUIDES which
need to be stamped per square inch
which is why we use a COMPUTER ALGORITHM
to solve the Complex Pathways Routing Problem!

a reply to: StargateSG7

While it has been a while since I have done a post on this thread,
I can assure you we are STILL doing ongoing research on this
OPENSTEALTH PROJECT to research a truly PASSIVE visual stealth
panel that can be manufactured using modern BUT CHEAP-TO-MAKE
glass-master stamping technology.

One key issue on the mapping and creation of optical waveguides
in a plastic substrate is the "Most Optimal Path Problem".

For each 1 inch to 2 inch square panel, I must not only INGEST
new paths of light coming from the surface-lens structure
of a rigid optical stealth panel, but I ALSO have to pass
through all the beams of light coming through wave guides
that are from ALL OTHER CONNECTED optical stealth panels.

My original plan was to use an advanced path-finding
software algorithm to find an optimal optical path structure
that incorporates all waveguides from connecting stealth panels
to other connecting ones using a LAYERED approach where specific
panels will be assigned a specific layer of pass-through optical waveguides.

This unfortunately is an ABJECT FAILURE and the end-result is a
prime example of where "Exponential Scaling" rears its ugly head!

To illustrate:

a) We have 10 surface lens by 10 surface lens optical stealth panel.

b) that 10 x 10 series of optical waveguide inputs must be ingested
into the stealth panel and all 100 inputs must NOW be rerouted to
the next stealth panel AND still allow the pass through of all light
beams from ALL PREVIOUS stealth panels. This number of inputs
and outputs exponentiates as we keep adding more and more
stealth panels to a structure. This also means the sheer number
of optical waveguides that need to be stamped into the plastic
substrate ALSO exponentiates.

c) This makes the thickness of the optical stealth panel increase
by the number of layers needs pass through all previous waveguides
from ALL PREVIOUS stealth panels.

d) if you start the multiplication process using 2 inch by 2 inch stealth
panels, the number of layers needed for optical waveguide pass-through
makes this multi-layer approach very EXPENSIVE...!!! While Technically
POSSIBLE to create such as structure, but weight-wise (i.e. a person
covered in 2" inch THICK optical panels is quite IMPRACTICAL for
carrying by oneself) its a BIG PROBLEM.

As per the above issue, the use of multiple layers of stamped optical waveguides
within an optical stealth panel to pass-through all previous optical stealth panels
is impractical and too heavy for comfortable wear by an average person.

HOWEVER !!!!!!!!

One optical sciences specialist which whom I have judicious contact with,
has outlined a specific quality of light that may be of some use in my quest
to provide CHEAP and ABLE optical stealth panels to the open market!

The Wave/Particle Duality of Light can be EXPLOITED such that MULTIPLE
BEAMS OF LIGHT can be PASSIVELY MULTIPLEXED through a single optical
waveguide without causing interference between and to other beams of light!

This allows me to multiplex all INCOMING beams from the surface lens structure
of a stealth panel into ONE SINGLE optical waveguide and have that wave-guide
carry and then de-multiplex all the light beams at the same intensity and same
2D-XY placement to the OUTPUT stealth panel as from the INPUT stealth panel.
The output panel is, of course, placed on the other side of an optically-stealthed
person or structure.

What was outlined, gave me an EPIPHANY that has allowed me to
to concentrate on creating a FACETED SINGLE OPTICAL WAVEGUIDE that
bounces light waves from a SPECIFIC 2D-XY INPUT POINT to the same
2D-XY output micro-lens location of the output stealth panel as was
on the INPUT stealth panel!

To use an analogy, I'm creating a hall of mirrors where each mirror is
angled and placed in such a way that ONLY the imagery from a specific
input location is bounced to the next specially placed and angled mirror
assigned to that INPUT LOCATION ONLY. This SINGLE "Hall of Mirrors" has
thousands of specially placed and angled mirrors places on the sides, ceiling
and ground-surface. Each mirror bounces along ONLY the imagery assigned to it,
which means I can use ONE HALLWAY (i.e. optical waveguide) to carry MULTIPLE
BEAMS OF LIGHT and have them NOT INTERFERE WITH EACH OTHER!

This gives me the room to use OTHER hallways (i.e. waveguides) to
PASS-THROUGH the light coming from ALL PREVIOUS stealth panels.
By using some advanced pathway construction algorithms, I can
create faceted optical waveguides in a stealth panel such that
each panel can PASSIVELY be assigned a specific INGEST POINT
or OUTPUT POINT simply by properly manipulating the
"Angle of Incidence" for each input micro-lens and
properly angling and placing a series of embedded
optical waveguide facets so that the incoming
light beams gets bounced around to other
assigned facets which will eventually output
to a PASSIVELY ASSIGNED output stealth
panel and 2D-XY micro-lens point.

This faceted optical waveguide structure
CAN be stamped at a high-enough resolution
and quality of build that it is STILL ABLE to
be created using the multi-layer Glass Master
Stamping method to create CHEAP and
LIGHT WEIGHT optical stealth panels.

---

I will display a CAD-type drawing which illustrates
the Faceted WaveGuide concept later in the week.

a reply to: StargateSG7

An interesting update to the OpenStealth System
using 3D-printed waveguides as visual stealth.

As of September 2016 having had lots of access to some
ridiculously fancy computing gear for doing some optical
modelling, we have figured out a way to use SINGLE wave
guides (i.e. optical pathways) to allow specific wavelength
to be reflected into specific optical path entrances/exits
using a technique we call:

"Optical Pathway Direction via Differential Wavelength Absorption and Reflection"

Technically, it could be considered a Metamaterial construction
since we have to use microlithography to construct the 1" by 1"
or 2" by 2" visual stealth squares which form a passive visual
stealth system.

The key function that is allowed by our technique is that
at the microlens entrance/exit at the top surface of the
stealth squares, an optical pathway is lithographed
such that a SPECIFIC ANGLE of reflection is assigned
to each input microlens and the light waves of the
icoming light is bounced along the wave guide
at a specific angle. Some angles will be steep
and thus finely sawtooth shaped while other
angles will be long and the bounce profile will
be longer between each reflection.

The key issue is that specific mirrored surfaces
can be "grinded/etched" into a SINGLE optical waveguide
where all along the walls of said waveguide will
contain a specifically calculated mirror angle that
is assigned to a specific input-micro lens and that
reflection path is MAINTAINED to the next connected
square such that the front visual stealth squares covering
the "Stealthed Object" has incoming light waveguided
(i.e. reflected) along a specifically angled path that is
replicated at the exit microlens at the BACK of the
"Stealthed Object".

Of course, we DID have to take into account flexion
of the wave guide as a wearer of the stealth squares
bends, walks and does other physical activity thus
changing the angle of incidence for each light path.
This also includes the flexible optical connections
between the individual stealth squares which also
needs to account for changing the angle of incidence
for each assigned waveguide input/exit which is
where we run into an optical wall !!!

As the squares get smaller and thinner the precision
of the waveguides and micro-mirrors must get ever
finer and more precise and as the squares bend/flex
the waveguides do the same and send the wrong
lightwave to the wrong exit.

The LARGER the square, the more rigid can be made
the "Stealth Square". This means the larger the
micro-mirror can be within a wave guide allowing
for more angle-of-incidence variablilty thus allowing
better lightwave control. The optimal size is a
MINIMUM size of 6 by 6 inches for rigid squares
with 0.2 to 0.5 millimetre sized microlenses to
make the number of assigned angle of incidences
manageable on a mathematical and lithographic
basis. Anything smaller and you will get problems
such as the light from an incoming square being
sent to the wrong output square AND where two
beams of light start bouncing off the same reflective
surface and then summing to give you luminance
changes and chromatic issues making your visual
stealthing ineffective!

So on the balance of things, some reasonable
moving forward on this project has been
accomplished. A second path of exploration
is the recent changes in PRICING of flexible
circuits and nano-LED now ALLOWING the
ability to create low-powered networked
squares that can input light, then digital
signal process it for enhancement, compression
and short-distance communications to an
assigned output square for final emissions.

This is basically similar to wrapping a person
or object in micro-cameras and micro-television
to MAKE an obejct appear invisible on an ACTIVE
basis which THEN ALLOWS said covered object to
be MANAGED for desired visual emissions.
i.e. a scenario where a tank can be made
to look like a cheap truck or a turn a person
visually into having the visual profile of a
large animal or be part of a building surface.
This is a form of ACTIVE CAMMOUFLAGE
used CHEAP micro-printed flexible electronics
and very low-power networked communciations!

These ARE exciting times ahead and I will update
this posting series every few months until a
PURCHASEABLE and USABLE visual stealth covering is made!
