Abstract

Real time generation has been achieved for 8K full color rainbow hologram with normal PC. We extended previous 4K rainbow hologram calculation to 8K resolution, 7,680 x 4,320 pixel. The hologram is calculated with a line source approximation that can accelerate computation speed faster than the previous slit model based on image hologram calculation. Experimental results show that holograms are generated and displayed about 18 frames per second with 140,000 points. Additionally, the current line source model calculates 8K holograms 1.6 to 2.3 times faster than the previous slit mode.
