A number of people viewed the video. According to this company, what they
did is totally new in 3D. Does anyone know with any certainty that the technology
here is really new, or has this been done already? That is, using only a laser to
display a 3D image in the air (or water)?
I would think that this technology could have a great many uses in the future,
once/if it is perfected over the years.
I guess no one knows. That's ok. I tried to find more information. There is
very little at this point. Probably because it isn't a ready for prime time product.

Although today we can witness a lot of so-called 3D display on the market, they all make use of a technology that tricks human brain into thinking that the person is watching 3D content. The latest invention, however, does not provide an optical illusion but can naturally show 3D content in the air...without any screen.

While most 3D displays available today involve a form of optical illusion that depends on the parallax or disparity inherent in human binocular vision, this new system, which can function in air... ,needs no screen of any sort...

"Most current 3D devices project pictures onto a 2D screen, and make the pictures appear 3D through an optical illusion. But this device actually shows images in mid-air, so a feature of this system is that it enables 3D objects to be viewed naturally." said Burton engineer Hayato Watanabe.
The Burton system functions by focusing laser light into points which stimulate oxygen and nitrogen molecules in the air to a plasma excitation level. Computer control of the laser's position can cause the dots to coalesce into recognizable patterns very similar to a hologram, but literally in thin air.

Amazing thanks. I had seen a light show emitting a bunch of blittering rays displaying 2d images in some kind of gas in the early 90's, but not to this degree of 3D and that amazing show of triangles seemingly floating in the air.
