I didn't forget about you.

DASAR was your acronym, so for that one you can have all the (imaginary) royalties.

But ARGB is MINE!
Unless of course you help in developement. Then we can share..


The Anti-RGB idea is actually quite good, what do you think?

Instead of projecting light, taking light away, leaving only the thing you want to be seen...

Now we need investors.. Did you check the prices on anti-photons? The anti-green ones are way beyond my budget...

ARGB technology is what I call real outside-the-box thinking
In fact I believe we could eventually do away with the box altogether


There may be an opportunity for value adding here if we take the more common coloured (hence cheaper) anti-photons and mix them to produce resultant pseudo-quasi-antiphotons in a more exotic range of anti-hues.

Oh - don't rule out the use of anti-phosphors which could theoretically be excited by a bombardment of standard photons if the wavelength is suitably short. I wonder if these anti-phosphors are capable of aerosol distribution?

On a more serious note..


The AntiRGB and taking light away wasn't completely a joke.

It was actually the only way i could come up with, for projecting "holograms" into daylight.

Unfortunatelly, anti-photons don't exist. And in the oppinion of some quantum physicists, neither do photons.


Even tho antimatter does exist, anti energy or (anti light) doesn't.

Energy doesn't have a counterpart. But it is possible for energy to "annihilate" itself - if you have two waves completelly (180°) out of phase.

It's called interference. It can be constructive or destructive. If two waves are in phase, they amplify each other, if they are out of phase, their combined amplitude is zero..


It works with light as well, but you can not put two light beams directly on top of each other from different sources.. You have to use a source and use two incredibly small slits (so only light in one polarity can pass) Then you get interference patterns. In some spots they are dark, and in others they are brighter than any of the two beams would be by itself.

Any way, it would be impossible to use it to annihilate "pixels" in mid air, to create the anti-hologram in my hypothetical idea.

Still, Anti-RGB was the best i could come up with.


If we ever have real "holograms" visible in daylight without any medium other than air, it's gonna be one hell of a technology.

But if such technology should ever be developed, i seriously doubt it will be called a hologram or done with lasers.

I read this interesting article about a new type of beam weapon that actually creates rainbow colored backgrounds in any location and the only residue, carbonated water, is ejected from an exhaust tube usually mounted on a lapel for stability.
The weapon is:

Advanced Scanning System andComplete Lepton Origination with Warp Negation

Now you're getting with the program...

?

You lost me at "and".


On the other hand, i found something that may have been used in the creation of those nasty 911 holograms - Anti-Light.


Anti-Light creates actual darkness, unbroken by torches or lanterns and impossible to see in. However, Anti-Light does throw Anti-Shadows: bright spots of illumination that can be used to find your way around in the case of a sudden surge of Anti-Light.

Question:

Do you really turn the light on or simply turn the dark off?

Well believe it or not, there are people who would accept the theory that a lightbulb works by sucking the darkness out of the room which is the very principle needed to make these negative holograms work.

I remember having a dream about mercury and a rocket hologram materializing before my eyes, and firing off. At the time, the area was being invaded by aliens and spaceships were everywhere.

I tried to google something along the lines of mercury hologram, but came up with nothing. When I was dreaming, it made so much sense. I totally had an "a-Ha" moment.

Has anyone else heard of mercury and holograms before? Or am I just an idiot?

Leira7, not exactly mercury holograms but holograms involving the use of mercury:

hyperphysics.phy-astr.gsu.edu...

Perhaps, you were cat napping through a televised science program at some point in time, and that program was discussing holograms and mercury?

I was asleep in my bed. I don't really watch tv anymore and I am not into science like that. I can't believe they exist, I seriously thought my mind was making things up again. That kinda freaks me out now.

A little bit more about holograms...


I was trying to figure out, how the ViZoo Cheoptics 360° projection system works.

After all we were discussing in the last few days, this wasn't so hard to figure out actually.

What tiped me off were the angles of the glass panels in the reverse Cheoptics pyramid..


It's the same principle as used by the Musion Eyeliner.
The only difference beong, that Musion uses only one projection screen (the foil tilted at 45° in front of the stage), while the ViZoo Cheoptics uses four such tilted glass plates.

The only way four 45° tilted glass plates would fit together is a pyramid.

After that, they just use four normal High Definition projectors, one for each plate.
Every projector shows the image taken from a different angle.

But there are just four angles used - front, back, left and right.
So the ViZoo projection system isn't real 3D either.
As you walk around the pyramid, and move between two plates, you suddenly see the object presented from a different side.

This would be very noticable, so they conceal the edges of the glass plates with a black support, which is slightly wider than would be needed to hold them together.

The result is an almost smooth transition between the four images, as you walk around...


What this means is that the projected images are not really 3D, and they are also not "floating" inside the chamber. They just appear to be. It's just an improoved version of "Pepper's ghost".



OrionStars once asked me which hologram doesn't use lasers.. Even tho before the invention of lasers there were succesfull attempts at creating holograms, nowadays all holograms use lasers.

But the problem is something else..

The word "hologram" doesn't mean a 3D image projected in mid air or a medium.

Holograms are those pieces of film containing 3D images created by the interference of two laser beams. This is the original meaning of the word.


The only reason we think of holograms as 3D objects floating in air projected by lasers is science fiction.


All of the "mid air floating" visualisation systems presented so far, were simply 2D projections on some sort of medium.

The only real 3D projection we've seen was that fast rotating mirror.
And the mirror is again tilted at 45°, which means it's an even more improoved version of the Pepper's Ghost illusion, only this time projected from a much larger number of angles.

And even this can provide real 3D appearance only in the horizontal plane.
The vertical plane is simulated with head (or in the case of the video - camera) tracking.


The only thing i wasn't sure about were those two girls dancing on a stage. I thought that might have been a real "hologram", but since it was created by ViZoo it is probably again just another example of Pepper's Ghost.


If that guy would have patented it, his grandchildren would be filthy rich by now..


Anyway, my point is, that the word "hologram" is very misleading.

If we ever invent something that really can project real 3D images in some sort of medium or even air, it won't be called hologram, and will require much more than just lasers.

That we could justifiably call magic

For now - smoke and mirrors are what it takes to get anywhere near convincing and that's on extremely small fixed displays, not open air.

To reproduce a holographic image of an object the size of a 767 raises the question of how that image could be recorded in the first place?
That could prove even harder than the challenges of playing it back life sized.

While we're on nifty 3D displays I once saw one for an arcade type game that used a pulsating flexible mirror to reflect the images from a CRT. The image frames were synchronised with the mirror movements to make a very convincing illusion of depth. Again very much limited to the box it lived in plus specialised hardware and software.

You've made a CRAP LOAD of good points. I think the word hologram has actually lost it's true scientific meaning and so it's misused a lot.

Here's a few other examples of words that have lost their original meaning.
THEORY-This word once required evidence to support it but it's been so misused anyone without any evidence now states they have a THEORY.
EVIDENCE-The word is now apparently used as an identifier for one's opinions

It's also interesting to note that many of the most convincing displays are not laser holograms at all.

Thank you very much for you input. Might I respectfully suggest that you post the information you are talking about. It defeats the whole community aspect of the thread to ask everyone who is participating in the discussion, to go off on their own and look up the information. It would be very helpful to:
Post specific details about the subject
Mention whether the information is opinion or factual based.
Cite source material.

This will greatly improve future discussion and help prevent anyone from being overlooked.

Thank you very much !

Yes, I've noticed that as well. Just curious but are you or is anyone else familiar with any of the DARPA projects regarding holography?

All I've heard about DARPA laser holography (well the credible tales anyway) is to do with very high density data storage and retrieval and the generation of 3D map displays in portable units for field use. It could lead to consumer systems using glass discs with terabyte storage capacities which would make home 3D movies a reality in the near future.

The wackier fringe has them faking UFOs and armies on the ground etc.

I've also read a few things about holographic radar but haven't been able to find much credible info about it to this point.
