We Want Our Holographic TV
Hold on to your hats, 3D TV is here!
The heart of the system is the digital light processing micro-mirror chip, made by Texas Instruments and currently used in television, video and movie projectors.
These devices incorporate a computer that processes an incoming digital signal several thousand times a second, changing the angle of each micro-mirror to reflect light from a regular light bulb. The resulting image is a two-dimensional video projected onto a screen.
One of Garner’s innovations was to replace regular light with laser light. Such light is coherent, meaning that it comprise light of a single wavelength, with all light waves travelling ‘in phase’ with one another. Light from a white light bulb comprises many different wavelengths that are out of phase.
Interesting that essentially they are using off-the-shelf technology with some modifications. They still predict that we won’t see commercial 3D TVs until 2020 (and if the adoption of HDTV is used as a guide it will probably take 100 years longer than that).
