摘　　要：基于液晶空间光调制器的高分辨率及其像素的微尺寸,分析了液晶空间光调制器用于数字全息图光电再现时的视角问题,并由此提出了通过空间三屏拼接的方法增大再现像视角的方法,进而利用电寻址空间光调制器的时间分辨率实现数字全息图的实时动态显示.利用经过改造的液晶背投影光学引擎系统设计了硬件实验系统,给出了实验结果.Based on the high resolution of Liquid Crystal Spatial Light Modulator and micro size of it＇s pixel, the problem of viewing angle of the reconstructed image of digital hologram using Liquid Crystal Spatial Light Modulator was analyzed and a method for enlarging the viewing angle of the reconstructed image was proposed by means of jointing with three SLMs in space. The real-time and dynamic display was implemented by utilizing the time resolution of the electronically addressing spatial light modulator. The experimental system was designed based on the improved optic engine of liquid crystal rear-projector and the experimental results were included.
