| Abstract(in English) | Electroholography can reproduce all the depth cues required for human perception of depth, and is attracting attention as an ideal three-dimensional image presentation technology. On the other hand, the computer-generated hologram (CGH) used in electroholography has not yet been realized due to its high computational load. In this study, a special-purpose computer for electroholography was developed using the Xilinx Alveo U250. The special-purpose computer is capable of computing a CGH of 1,920×1,080 pixels at 28.9 ms (34.6fps) from a point cloud of 49,665 points. Its performance is 230 times faster than the CPU (Intel Core i9-9900K) and 7.43 times faster than the GPU (NVIDIA RTX 2080 Ti). We demonstrate the architecture and computational performance of the developed computer. |
