【摘要】 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。更多还原

【Abstract】 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.更多还原
