Narrow band mirrors composed of a polarizer, a stack of lossless birefringent crystals, and a conventional mirror are described. Curves showing the reflectance characteristics of the mirrors are included. Design data are tabulated for narrow band mirrors that have appreciable between-peak reflectances because of the Gibbs phenomenon as well as for slightly broader band mirrors with lower between-peak reflectances. Computations are presented in a series of graphs to demonstrate sensitivity of the response to the angular adjustment of the crystal elements. Electric tuning of the birefringent mirror is possible and can be enhanced by a double element design. The choice of electrooptic birefringent materials and the temperature sensitivity of the mirror's peak wavelength are discussed along with applications. An appendix provides computational aids for the synthesis of birefringent filters.
描述了由一个偏振器、一堆无损双折射晶体和一个传统反射镜组成的窄带反射镜。文中给出了显示反射镜反射特性的曲线。列出了因吉布斯现象而具有可观峰间反射率的窄带反射镜以及峰间反射率较低的稍宽带反射镜的设计数据。通过一系列图表展示了计算结果，以证明响应对于晶体元件角度调整的灵敏度。双折射反射镜的电调谐是可行的，并且可以通过双元件设计来增强。文中还讨论了电光双折射材料的选择以及反射镜峰值波长的温度敏感性，并介绍了相关应用。附录提供了双折射滤光片合成的计算辅助工具。
