多级可调谐液晶滤光片的设计

Design of Multiple Tunable Liquid Crystals Filters

针对外加电压和液晶盒厚度的不同配置,结合具体设计实例,对多级利奥型液晶可调谐滤光片设计参量的选取和优化进行了讨论。在此基础上,将液晶和方解石晶体相结合,采用宽视场的设计方法,设计了四级液晶利奥滤光片。这种滤光片设计自由度大,可以在短时间内实现光谱的连续调谐。

Multiple liquid crystal Lyot filters with different configuration of applied voltage and thickness are designed , and designing examples are given. The selection and optimization of parameters are discussed in detail. Then, a four-stage liquid crystal Lyot filter inserted calcite is designed on the basis of wide field configuration. Calcite can make the design of liquid crystal Lyot filter more unrestricted. The Calcite-Liquid Crystal Lyot filter can implement continuous spectrum tuning rapidly.
