Real-time color electroholography using multiple graphics processing units and multiple high-definition liquid-crystal display panels

We succeeded in developing a prototype three-dimensional (3-D) color television system by holography using three graphics processing units and three liquid-crystal display panels for displaying three primary colored images. A 3-D animation system featuring holography is said to have potential for ultimate 3-D television. Because of the technical complexity involved, however, the practical use of 3-D television is difficult. In our system, the image processing speed for holography is more than 300 times faster than that of today’s personal computers, and a 3-D image composed of 1000 points can be animated at virtually video rate, although the image size is as small as 5 cm3. The system succeeded in producing realistic 3-D color animation.
