Holographic Keypads Float Into View 291
prostoalex writes "The New York Times tells the story of a Connecticut-based company called HoloTouch that is developing input devices that literally "float in the air". The technology will be licensed for information kiosks in New York city. Some other sample applications are available from the company's Web site. HoloTouch already managed to secure the patent on its technology."

From the website:

From the patent:
When a hologram is illuminated by a reconstruction beam, it produces a real image (which appears to be between the plane of the hologram and the viewer) and a virtual image (which appears to be behind the plane of the hologram). [snip] Thus, it is preferred that the holographic image 207 be a real image.
Quick review of holography: an extremely high resolution film takes pictures of the interference pattern generated when a coherent light beam strikes an object.
When coherent light of a similar wavelength later shines through this film, the interference patterns cause it to be shined through in exactly the same manner as the original coherent light, up to about half the resolution of the film. Most holographic film is 3000 lines per inch, so the hologram has a "resolution" of about 1500 lines per inch.
You see an image because the light reaching your eyes through the film is exactly as it would be had the object been in front of your eyes and illuminated by the original beam.
The light reaching your eyes is coming through the film and then traveling in a straight line from the film to your eyes. You can only see such light if the holograph is directly behind it, because the path of the photons cannot change after it passes through the hologram (disregarding minor lensing effects due to the atmosphere, that is)
What does this mean? Well if the hologram appears to be one half meter in front of you and the holographic film is one meter in front of you, and the holographic image appears to be 10 cm x 10 cm, then the minimum possible size for the holographic film is 20 cm x 20 cm.
I don't call that entirely independent; as a matter of fact, it's a pretty simple relationship governed by a version of the inverse square law.
Oh, an interesting fact about it is if you take a holographic film and cut it in half, because all the information about the image is stored throughout the film, you don't have half a hologram; you have a hologram of the entire object that is half the size of the original. Pretty cool stuff actually.

Amazingly, a hologram may be cut in half and you will still see the entire image. And you can cut one of the pieces in half again and again and see the entire image. Every part of the hologram has received and recorded light from the entire object!
Now how does it work? Basically, a film hologram is more than just a fancy trick you are playing with light; the entire piece of film is involved in recreating the image. Every piece of film holds all of the information about the object and they all contribute to the whole. By reducing the size of the film; you simply reduce the size of the object.
A better explanation: http://www.emergentmind.org/miller-webbI3b.htm
oh and as for other neat treaks with film holograms? Let's say you have a complicated, fussy optics array. You spend days tuning it and getting it perfectly in focus. Now let's say this optics array is going to be used to focus the aiming laser on an abrams tank. Or as the projection lens for the periscope in a submarine.
You COULD ruggedize the whole setup, and field tune it occasionally.
But you could also use holography; you take a hologram of the entire setup, and the hologram acts exactly like the original optics, up to the resolution of the hologram, at the wavelength you used. You can make what's called a whitelight or broadband hologram.
