摘要：We developed a simple electroholography system consisting of a graphics processing unit(GPU),which has been developing quickly in recent years,and a PC projector,which contains a minute reflective liquid crystal display(LCD).The structure of the GPU is suitable for calculating a computer-generated hologram(CGH).The calculation speed of the GPU is approximately 500 times faster than that of a central processing unit(CPU) alone.We succeeded in reproducing a video of an object,which consisted of 256 points in about 20 frames/s.Reconstruction at the video rate(real time) was almost completely achieved.Moreover,we used a PC projector in which minute reflective LCD panels were included as part of the reconstruction optical system.Three LCD panels for the three RGB colors were built into the inside of a projector.Using them,holographic reconstruction with color was also able to be performed easily.This system,consisting of a GPU and a projector,is simple to make.Therefore,this system is expected to promote reserch in this field.
