摘要
对液晶投影显示系统的偏振器件进行了研究,提出了一种新型偏光转换装置的设计方法。整个装置由两组微透镜阵列、一块光学性能良好的方解石晶体和一些半波片组成。微透镜阵列对入射光进行空间分割;方解石晶体进行起偏;半波片起相位延迟作用,从而实现从非偏振光到线偏振光的转换。用晶体偏振光学理论对该系统进行了理论推导,并用Zemax软件进行模拟。结果表明,系统的光利用率为86.1%,消光比优于10-3。该系统结构简单,性能稳定,但通光面积较小,适合与1.8cm(0.7in)以下的硅基液晶面板配合使用。
The polarizing conversion system （PCS） of LCD project,on display is studied of design PCS is reported. The novel PCS consists of two groups of microlens array, a calcite plate and some half-wave plates. The microlens arrays average the collimated light. The calcite works as a polarizer. The half-wave plate works as retarder. Accordingly polarizing conversion is achieved. Crystal polarizing optical theory and software are used to deduct the performance of the device. The result is that the efficiency of light conversion is 86.1 %, the extinction ratio excels 10^-3. The PCS has a simple configuration, steady performance, but a small work area. So, it adapts to the LCoS panel which diagonal is less than 1.78cm（0.7 in）.
