Remember the empourer in Star Wars? He spoke to his commanders via a Hologram via great distances. Is this possible in 1999?

My first impulse was to say that it's impossible. On second thought, if you look at the quality of the hologram 'movies', I'd guess that it might just
be possilble, given the very low quality of the holograms shown. I've seen some amazing pictures that were done with VERY primitive computer generated holograms. I don't think you'll see it happen soon though, unless by some technological breakthrough new ways of capturing, compressing and displaying the information needed... 63.64.148.161

I'm working for a year now with the idea
what I did was to get an X,Y and a Z axis
X and Y are simple opto-acoustic mirror settings (working)
Z axis ? power on the laser ?
charging the air ?
any Idea's are very welcome

I think about a film that are a PLAIN image created by the interferences of direct
and reflected laser lights... so may be possible to "send" this plain image through
internet and create a new copy ussing a film.
Probably for more accuaricy and movement, film would be replaced by a ultra
high resolution LCD, than can show the interferometry whith a pointing monocromatic
light . 195.53.164.116

A few years ago, I saw a video arcade game that projected real images above a horizontal glass screen. It appeared to use real film
film footage probably taken from two cameras to give a stereographic effect. My guess is that it was projected onto a screen
somewhere underneath and then used optics to generate a real image that seemed to project up from the glass surface of the game.
I think the same principle was used in a novelty item from edmund scientific that used two concave mirrors to project a real image of
an object through a small hole in the top mirror. 137.240.230.236

Memo for Jburnfie, I too have seen years ago a video game where a moving image of a woman apx 4 1/2" tall was syncronized with a voice track. This made it seem that she was talking. I have a project where by, I would like to do the same except on a larger scale. If you remember the name of the Mfg. can you e-mail it as well/ Att: Haddan Hadden their is a japaneese company that I came across years ago that made moving hollograms,unfortunately I don't remember the name of it.And today I seek it too. If I Discover any further news I will get back to you both. Please do the same if you gentelmen come across anything.
If their is anyone else with info that can be of help please reply. (: 207.253.95.26

I'm using someone elses connection so don't try to e-mail me:) Regarding the "holographic" video game I saw one where characters interacted in the middle of a flat piece of glass and seemed to be standing on it. On closer inspection I found that it consisted of a curved mirror in front of a regular crt screen. Ingenious, but not holographic. The initial illusion was inhanced by the large graphic on the side of the game indicating it was a hologram! 209.156.166.128

Re: INFORMATION BARRAGE!!!
I saw one of those video games you were talking about. This one was called "Time Traveller," Sega 1991. The local Museum of Natural Science (Houston) has similar exhibits in their petrochem section using flat clear glass plates reflecting the actors (as floating 2-d images) from hidden monitors, so they appear to walk through and interact with the exhibit models. Very cool Pepper's Ghost application.
The parabolic mirror toy mentioned above is called "Mirage."
Had occasion to do some research on 3-d real-time displays. Here's some links that might answer some questions:
On Star-Wars-esque floating holograms (the answer is "not really, but almost"). Also see the bit on "Pepper's Ghost" for the ghost hologram (or one way to do it):
http://www.pangolin.com/resguide03b.htm
On 3-D real time displays- volumetric displays can give real-time 3-d displays, but you can't stick your hand through them. They use laser or camera projections on a rotating screen. Many links on them, here's one:
http://www.actuality-systems.com/
This company makes parabolic mirror based advertising displays, including a display using some kind of CRT arrangement, presumably computer driven. This would seem to be the closest thing to the 3-d floating Princess Leia/Admiral Whatshisname communicator:
http://www.3dmedia.com/
These guys are working on making a 3-d display system using lasers intersecting in a cube of glass doped with some kind of exotic chemicals. Not charging the air, but a start:
http://www.3dtl.com/
(As an aside, I'd worry about using lasers powerful enough to charge the air- I've seen pictures of lasers focused to points tight enough to convert the air to plasma, but they were too powerful to look at, I'd think. Maybe a dust cloud of some kind of fluorescing material, energized with UV lasers interecting at th appropriate points? {Shrug})
Here's a link explaining how the video game and similar arrangements would work (uses a light bulb, but same idea):

hello holograms produced in space is possable and has been done. try diffrent aproch use light waves, conflicting beames, high
frequinces and dont get in the path of the light, high frequinces penatrate body use thrid cancelation frequince to create walk through
hologram. lastly high power computer, once you figer out how to do it, an imageing system will need to be programed to produce
motion holography. good luck 129.115.55.115 129.115.55.115

I was thinking of using a lcd screen that would rotate at high speed- the image displayed on the lcd would be timed just right to make a fake hologram- dunno, also with the respect of using two lasers to make a dot at there intersection is damn near impossible- unless the lasers are VERY focused- so, the next step i think is to figure out a way to cheat a holographic display, not just a 2d image floating. if anyone wants to share ideas my e-mail is FormaT411@charterTN.net 12.21.196.216

GizWiz - Fri, Mar 23, 01 12:00:14 PM
Holograms are actualy very simple. The technology to create them is dificult. Imagine a cone extending from your viewers eye onto the 'Image' you wish them to see. Then continue that cone on to a projection device of some sort. The size of the cone when it reaches your 'projection' device will indicate how large of a projection array you will need. Next you need to understand how we see. Every photon of light that strikes a object is not refelcted back into your eyes. So ignore any light that does not concern your viewer for now. Concentrate on only the cone we created earlier. The light rays from your holographic object must be identical to those that would be created if an actual object were there. The Array I spoke of can end up being very large depending on how far away the object is from the array. Basicly the array will end up being millions of micro mirrors. Just like a Raster scan Computer monitor, a 3 color system (Red,Green,Blue) can be used to create colors. But adding to the complexity is the need to tilt and swivel each of the micro-mirrors so that the original photons paths are replicated by your hologram. Holographic photos do with by using the silver in the film and exposing the film to a interference pattern created by mixing a image light source with a Reference light source. In our electronic system the advantage should be in the ability to instantly adjust the mirrors angles and provide an active disply.
Hope this helps. Mike@theatronics.com 63.79.77.125

Michel - Tue, Apr 24, 01 07:31:46 PM
Hey, well if youve read all the postings youll have read that there is a small device known as the "mirage". This thing is not just a gimick or dead end. It reflects the image location points and potons and intersects then above it by way of two parabolic dishs. It is very simple and very useful. You can buy them for a low cost of $30 compared to expensive lazers and eguitment. Recently I have been working on a project that has achieved a moving picture hologram using this aparratus and its alot simpler than intersecting lazers. Any one who wants to talk to me can contact me at caliban61@hotmail.com. (oh put subject as Holograms)
207.192.130.182
FYI - Wed, May 30, 01 12:35:43 AM
The U.S. Military in the early 90's, showed off a device to create "Virtual Holograms." It was a spinning helix about eight feet high with laser(s) pointing up and synchronized to the moving surface of the helix.
I saw this on an educational program some years back, but remember that it had the potential to project animation.
As you might expect, it was a fairly primitive image produced of red dots of light that you would see from a laser pointer today. It reminded me of the 80's video game battlezone, which was basically a wireframe tank game, or you could also liken it to a laser light show at a concert.
Since the helix appeared to be constructed from metal, a person would not be able to walk through it.
Conclusion, the premise is proven and if it were given some support by a company with an R&D budget for new video technologies, could develop into a cheep and common standard for public promotions and the like.
All you would need to produce full color would be that elusive blue laser and some realtime 3-D projection software. 24.29.132.210

First off, Nathan Walton is cool. I like his input.
Secondly, A recomendation on hollographic imagery is projecting lazers onto smoke. It could work where slices of the image are projected onto the smoke via lazers to create a full transparent 3d image.
But the intersecting lazer sounds pretty feasible even though it sounds expensive.
I'll do more research and get back to you.
Oh by the way, in popular mechanics volume 178, no.10, there was a small article on the "Vision Station", a high resolution image projected on a curved screen that circles a user's entire field of view.

I read not too long ago, that with an extremely fast pulsed laser, a group of scientists were able to produce a "star" in the night sky. I may have read this wrong, but it seems they somehow created a point source of light at some distance away. Extrapolating this technology, wouldn't it be great for holographic type projections?

joseph - Fri, May 31, 02 12:22:46 AM
A way of projecting an image that would appear to be floating is actually
quite simple, though disappointing. The way I figure you could or can do it is by either setting up a series, or a single yet broad jet of either mist or smoke. Wen the water or smoke is spewed out, it will be in a flat manner as to make a slightly visible screen. Using a projector at the base of the screen, the image will be projected as if it were squashed, but on the screen it would appear normal. The projector, of course, would be at an angle. For the mist, there would be some sort of devise that would take in the used vapor and cycle it through again. Something similar would be used for the smoke version. The disappointing part is that it would be 2d. Thanks for reading. 66.118.198.193
