高性能LCoS投影系统光引擎

硅基液晶作为投影系统空间光调制器是一个相对较新的技术，因为其成本低，光学效率高，具有很好的发展前景。使用LCoS面板作为光引擎的结构较多，这些结构各有优缺点。一个系统的亮度、色阈、对比度主要取决于它所采用的光学引擎。文章通过对几种LCoS光引擎的分析和比较，得到了一种高亮度、高对比度、宽色阈的光引擎结构模型，为实际设计提供了依据。

Optical Engines for High-performance LCoS Projection Systems

Liquid crystal on silicon (LCoS) is a relatively new technology that can be used as the spatial light modulator in projection systems.It has a great developing potential for its low cost and high performance in optical (efficiency.) Various optical architectures have been proposed that can be used with LCoS panels. All of these systems have their own specific advantages and disadvantages. Efficiency, color gamut, and contrast ratio are three quality parameters that are largely dependent on the optical engine. By the analysis of several optical (engines,) we got the best structure of the optical engines which can get the best bright and contrast rate, large color gamut, which providing design basis for the practical project.
