University of Texas professor develops holographic video technology

UT Southwestern Medical Center features a press release about a new holographic video system developed by a professor of biochemistry.
In a small research laboratory at UT Southwestern Medical Center, a grainy, red movie of circling fighter jets emerges from a table-top black box, while nearby, a video of a rotating human heart hangs suspended in a tank of gooey gel.
These images - the first true, three-dimensional, holographic movies - are the brainchild of Dr. Harold "Skip" Garner, professor of biochemistry and internal medicine at UT Southwestern.
The technology shows promise for medical visualization and heads-up displays for helmets and military aircraft.
Also on the Popular Science list are a bionic eye, technology for a "smart" home, a tourist's spacesuit and the ultimate roller coaster.
"I predict that by the year 2020, that being the year of 'perfect vision,' we will have Holo TV in our homes," said Dr. Michael Huebschman, a postdoctoral researcher in Dr. Garner's lab and one of the developers of the technology.
Dr. Garner's holographic video system is based on complex optics principles, sophisticated computer programs, and a small computer chip covered with about a million tiny mirrors.
The heart of the holographic system is the digital light processing micro-mirror chip, made by Texas Instruments and currently used in television, video and movie projectors.
His signal is a sequence of two-dimensional interference patterns, called interferograms, which can be generated either from scratch or from data gathered from 3-D imaging applications, such as sonograms, CAT scans, magnetic resonance imaging, radar, sonar or computer-aided drafting.
"This technology is potentially powerful for medical applications," Dr. Garner said.
"We could easily take data from existing 3-D imaging technologies and feed that into our computer algorithms to generate two-dimensional interferograms."
On a computer screen, interferograms look like tiny random black dots similar to an off-the-air TV channel's "snow."
