摘　　要：分析了计算全息图编码原理,介绍了用MATLAB编程计算全息编码的主要步骤.用Matlab模拟了计算全息图的再现结果.将编码全息图实时输出到高分辨扭曲向列型液晶空间光调制器(TN LCSLM)上,和傅里叶变换透镜、滤波器、CCD等组成计算全息实时再现系统,实现了全息图的实时再现.最后,分析了提高再现像质量的方法.Firstly, the main progress of programming a encoding computer generated hologram （CGH） using MATLAB was introduced based on the analysis of the principle of CGH. Secondly, the result of the reconstruction of the CGH was simulated by MATLAB. Then, CGH was directly outputted on a high resolution TN-LCSLM, with Fourier transform lens, filter and CCD etc. , an real-time reconstruct system was stablished, and the reconstructing the CGH was succeeded real timely. At last, some methods for increasing the resolution of the reconstruct image were analyzed.
