The Japanese National Institute of Information and Communications Technology (NICT) has developed a color electronic holography technology that can project captured images of moving subjects under normal lighting conditions and reproduce them. Instead of a laser or darkroom, the technology relies on a video camera with a fly-eye lens and a number of integrated microlenses. The same lens is used to later display the 3D images. Prior to this technology, it was necessary to capture a stationary subject using individual red, green and blue laser beams in a darkroom.
With NICT's newly-developed technology, the hologram is produced from the captured video, after high-speed computing. It is displayed on red, green and blue LCD panels, before laser beams synthesize each aspect and display a color 3D video in real time. To date, the maximum size of the produced hologram is just 1cm (less than 0.4 inches), as the 3D viewing angle is limited to just 2 degrees. NICT hopes to increase the size four-fold, to about 4cm or about 1.6 inches within three years. [viaTech-On]
