摘要：
We demonstrate real-time three-dimensional(3 D) color video using a color electroholographic system with a cluster of multiple-graphics processing units(multi-GPU) and three spatial light modulators(SLMs) corresponding respectively to red, green, and blue(RGB)-colored reconstructing lights. The multi-GPU cluster has a computer-generated hologram(CGH) display node containing a GPU, for displaying calculated CGHs on SLMs,and four CGH calculation nodes using 12 GPUs. The GPUs in the CGH calculation node generate CGHs corresponding to RGB reconstructing lights in a 3 D color video using pipeline processing. Real-time color electroholography was realized for a 3 D color object comprising approximately 21,000 points per color.
