Japan’s AIST improves their 3D plasma projector

by DJ Neawedde | 17th July 2007

The Japan National Institute of Advanced Industrial Science and Technology (AIST) has improved the functionality of their 3D projector shown back in 2006 (video). The 3D projector uses focused laser beams creating flashpoint “pixels” in mid-air. These are generated as the focused lasers heat the oxygen and nitrogen molecules in the air, “causing them to spark in a phenomenon known as plasma emission. By rapidly moving these flashpoints in a controlled fashion, the projector creates a three-dimensional image that appears to float in empty space.”

Pink Tentacle also reports steps forward “include an improved 3D scanning system that boosts laser accuracy, as well as a system of high-intensity solid-state femtosecond lasers recently developed by Hamamatsu Photonics.” Improved image smoothness, resolution to 1,000 pixels per second, and image brightness/contrast control are some others.

      […] We’ve looked at set-ups like this in the past (see here, here and here), and this is one is also pretty impressive. “The display consists of a high-speed video projector, a spinning mirror covered by a holographic diffuser, and FPGA circuitry to decode specially rendered DVI video signals. The display uses a standard programmable graphics card to render over 5,000 images per second of interactive 3D graphics, projecting 360-degree views with 1.25 degree separation up to 20 updates per second.” Watch below… […]
