| Outline of Final Research Achievements |
Electroholography using computer-generated hologram (CGH) is considered to potentially realize the ultimate three-dimensional (3D) television. However, the practical use of real-time electroholography is limited by the complexity of CGH calculations and requires high-performance computational power. I developed the multi-GPU cluster system with 13 GPU boards and InfiniBand network. I implemented spatiotemporal division multiplexing electroholography to the developed system, and succeeded to display reconstructed 3-D movie consisting of 477,511 object points at 31 fps. Furthermore, fast time-division color electroholography at 20 fps is realized for a three-dimensional object comprising 21,000 points per color by using the developed multi-GPU cluster system. By applying time-division multiplexing method, I realized an easy-handling gradation representation of the reconstructed 3D object, and improved the image quality of the reconstructed 3D object comprising about 900,000 points.
