摘要
现已发现一种新型液晶盒工作模式，这就是液晶相位光栅模式，它是将空间周期电场加到介电和光学各向异性的均匀排列液晶层上而形成的。本文介绍了一种液晶相位光栅大屏幕投影系统，讨论了液晶相位光栅的基本衍射特性。
A new liguid crystal cell operating mode,liquid crystal phase grating, has been found.The phase grating is formed by the application of a spatially Periodic electric field to a uniformly liquid crystal layer with dielectric and optical anisotropy. In this paper, liquid crystal phase grating large screen protection system is introduced,and its fundamental diffraction characteristics are discussed.
