Holographic 3-D TV is not only possible, it's here
by Mike Adams, the Health Ranger, NaturalNews Editor
Holographic TVs have been a staple of sci-fi movies for years, but now the science isn't fiction anymore. A small-scale version of a three dimensional holographic television exists in the office of its creator, Harold Garner, a tireless 51-year-old medical doctor, plasma physicist and biochemist at the University of Texas Southwestern Medical Center. Garner created his holographic TV by making a variation on the design of a Texas Instruments digital micromirror device (DMD), which is currently used in high-end projectors. Now, Garner's challenge is to make a display screen (both mist and gelatin would work, but they diffuse the picture), and is working with a display composed of layers of microthin LCD panels. The primary applications for Garner's discovery will be medical, so it will likely be a decade or more before it finds its way to home theater systems.
Even if you had free run of any skybox in Madison Square Garden, you still wouldn't see half the action that you will in your own living room, one day soon, on a large-screen holographic television.
Without ever leaving your chair, you'll be poised to watch each play unfold from whatever perspective you choose, gazing into the depths of your TV.
The only thing lacking will be the soggy cheese fries.
Although this scenario is a decade away, a small-scale version exists today in the Dallas laboratory of Harold Garner, a tireless 51-year-old medical doctor, plasma physicist and biochemist at the University of Texas Southwestern Medical Center.
Garner's chair in developmental biology at UT is endowed in part by the founders of Texas Instruments, and the company gave him early access to a digital micromirror device (DMD) that is now used in high-end video projectors.
It is made up of nearly a million reflective panels, each of which can be angled by a computer several thousand times per second to reflect or deflect beams of light, producing moving pictures.
He programmed the DMD to reflect a sequence of 2-D interference patterns (called interferograms) that disrupt the laser light in such a way that it reflects a 3-D hologram.
To unfold the 2-D interference patterns into true 3-D images, the projection surface must have volume.
A column of mist will work, as will a tub of Jell-O, but both diffuse the projected image, marring sharpness.
So Garner is working with a display composed of layers of microthin LCD panels, each of which can, when electrically charged, be made clear or opaque.
Such displays exist today, but they work without the benefit of holography; instead they have to slice up a 3-D image and send it sliver by sliver to the LCD screens.
