Abstract

It is realized that real time generation of 4K (3,840 x 2,160 pixel) full color rainbow hologram on a personal computer without special hardware such as GPU or FPGA. Although the rainbow hologram sacrifices vertical parallax, it can be generated faster than image hologram and can be reconstructed full color image with single SLM. Holograms are generated over 10 frames per second with sub-million point cloud, converted from polygonal computer graphics data.
