一种应用于LCoS光机的复眼照明系统仿真设计

复眼照明系统利用复眼透镜，可实现高亮度和较好的亮度均匀性，并且有较成熟的偏振处理方法，在投影系统特别是基于偏振光的投影系统中能提供比光棒照明系统更加高的亮度和好的均匀性的画面，使得光能利用率和图像均匀性有了较大的提高。在对复眼照明系统的原理进行分析的基础上，设计了一种用于投影光机的复眼照明系统，并用Matlab对该系统进行了光线追迹的仿真程序设计。对复眼照明系统的光线追迹进行了仿真。实际应用证明，在LCoS中采用本方案设计的照明系统比光棒照明系统具有更高的亮度和更好的均匀性。

Design and Simulation of the Fly Eye Lens Array Used in the LCoS-Ray Machines

The higher brightness and the better homogeneity are achieved by using fly eye lens array.It seems that fly eye illumination system is the best choice for a good projection display system especially the system basedon polarization.Based on the principle of the fly eye illumination system,the ray trace illumination system is designed.The simulation program of the ray trace is realized by the Matlab.The results show that we can get higher brightness and better uniformity by the proposed system and the program...
