Lyot型双折射调谐滤光片特性研究

Analysis to Character of Tunable Lyot Filter

本文利用 Muller矩阵和 Stoks参量 ,从理论上分析 L yot可调双折射滤光片的透射率、通带半宽度等性能 ,并首次讨论了λ/ 4波片的精度对滤光片性能的影响。分析结果表明 L yot双折射调谐滤光片具有较好的可调性 ,可调范围较宽 ;λ/ 4波片的精度不会对滤光片的通带半宽度产生影响 ,但能引起透射光谱的移动。

Using Muller matrix and Stokes parameter,transmission and half breadth of passband of tunable Lyot filter were theoretically analysed,and the effect that the accuracy of quarter wave plate made to the character of filter was first discussed.The results show that Lyot birefrigent tunable filter has such properties as favorable tunability,wide tunable range and so on.The accuracy of quarter wave plate will do not any impact on half breadth of passband of filter,but may cause the moving of transmission spectrum.
