Man this is awesome.
Didnt they say like, 5 years ago, that holograms would be impossible to achieve in this fashion??
LIES


It's not a hologram. At all.

Except you can't, because that's not how a hologram works. This isn't one any more than those plastic film Pepper's Ghost displays.

Well, I suspect the mil ind complx has it already, but yeah, this is WAY cool.


Depends on which 'it' you mean. Plasma blooms have been known about for a long time.

What they're not showing in the video is audio from the scene where the display is running.

That's because it's noisy. Sounds like a buzzsaw.

This can actually be used to your advantage, though.

I can understand how this works in the X and Y axis,but how does it place a spot at a specific place (height) in mid air (Z axis)? I see this as the same problem they had building a working Jedi light sabre.It's easy enough to generate the beam to start with,but how do you stop it precisely at a fixed distance from the emitter?


There are a couple of ways. The way they did it in the 'Burning Bush' demo was to overlap a number of IR lasers so that the area of overlap passed the critical density and caused a bloom.

These guys do it by modulating the focus, I think. Their beam passes the critical density and blooms as the beam focus gets small enough, and you set the distance by diddling the focus. You might notice their 'voxels' aren't quite spherical.

Edit: OR a specific frequency strength from a single laser would do, too, probably, in that higher energy ionizes the air further away.



"frequency strength"?

I wonder if one day this technology will be placed inside of smart watches? This might solve the problem of the tiny screens.


Unfortunately, the air gets ionized, and ionized air (ozone, nitrous oxide) isn't really healthy to breath. There was also some research done on directly laser-scanning images into the retina using micro-lasers built into eyeglasses, but the idea of directly shining lasers directly into eyes never really caught on.

Oh goody, they'll be able to fake a fake Jesus coming out of the clouds to lead the righteous home.

If the Japanese are doing this openly and/or commercially now, then I have no doubt the US military could have used this covertly on 9/11 on the Towers.


would you settle for a Virgin Mary projection..I mean apparition ?
Because "they" have already done a few of these .

Stumason, yeah the pulses are high peak power, but they are also at a high'ish frequency. The average power is over 3Watts per dot I would bet and can still mark metals/skin right at the focal point because of the peak power. Not something I would call safe or a real breakthrough.

There's a much older one about the same thing when it was a uni research project I recall posting on with Wembley.

Ok thanks,so it will never be a nice compact self contained and single point system?

I'm sure it's greatly improved, the two units that 10th got during gw1 were bulky but were sort of aimed at a totally different end "user". Heh.

Sadly, Bush 1 decided not to use them. Alas.

we had them 10 years ago in Walsall and they used it to show a humourous version of harry potter story at a local light show in the park.



The Walsall illuminations? They used water vapour though, didn't they?


Ah, could have been that.
Sounds like Oec magic to me.

errr.. no.

The first one is a 2d projector onto a medium.

The second is an optical illusion 'hologram' that can only be viewed from certain angles.

This here is points of light in space that can be viewed from any angle.

But wouldn't a pulse that powerful, even though short make a devastating blow to an eye? I do understand my mistake with the watt thanks for pointing it out
but to ionize air even if short is a huge amount of heat and energy released. Can't wait til they tune it to real life standards though!

I'd imagine it would probably bugger your eye beyond belief, but then you can buy laser pens that can do that for £1 at the toy shop.

The medium is ionized air.

The second is still a hologram and you missed the most important part. It can be touched and felt.
