DARPA’s 3D Holographic Display Technology
The Defense Advanced Research Projects Agency (DARPA) has just completed a 5-year project called “Urban Photonic Sandtable Display”, or UPSD, that creates realtime, color, 360-degree 3D holographic displays. Without any special goggles, an entire team of planners can view a large-format (up to 6-foot diagonal) interactive 3D display.
UPSD is based on full-parallax technology, which enables each 3D holographic object to project the correct amount of light that the original object possessed in each direction, for full 360- degree viewing. Current 3D displays lack full-parallax and only provide 3D viewing from certain angles with typically only three to four inches of visual depth.
Looks like the technology was developed by Zebra Imaging, and is currently being deployed to an Air Force lab and two Army labs for use.
