摘要
基于方解石晶体光学特性和Wollaston式多光束分束棱镜结构的特点,以两晶体光轴夹角45°为例,利用折射定律和菲涅尔公式,通过Matlab软件系统的研究了Wollaston式多光束分束棱镜的光强透过率、分束角和平行分束距离随结构角的变化关系,通过结合玻璃棱镜,实现四束偏振光的平行出射。研究成果为Wollaston式多光束分束棱镜的设计提供了科学依据。
Based on the optical properties of calcite and structure characteristics of Wollaston multi-beam splitting prism, a beam splitting Wollaston prism was designed with 45 o angle between the optical axes of the two crystals. Relations between the structure angle and the intensity transmittance, splitting angle and parallel splitting distance were systematically discussed by using the refraction law, Fresnel formula and Mathematica calculations. And the structure angle was optimized. Through the combination of the glass prism, we achieved the parallel propagation direction of polarized light. The research results provide scientific basis for the design of Wollaston multi beam splitting prism.
