摘要
从棱镜的结构特点出发,利用折射定律和菲涅耳公式,推导了Wollaston棱镜对聚敛光的光强分束比随方位角的变化关系式。在入射角给定的情况下,分析了方位角对光强分束比的影响。结果表明：在入射角取定值时,方位角对光强分束比的影响基本呈二次曲线型变化；当方位角在160°～180°时,光强分束比最小。
Abstract
From the structure of the Wollaston prism, refraction law and Fresnel formula, a formula of relationship between the azimuth angle and intensity splitting ratio of Wollaston prism is derived when the incident light is spot arrest light. The influence of the azimuth angle to the intensity splitting ratio is analyzed when the incident angle is defined. The result indicate that the influence of the azimuth angle to the intensity splitting ratio is conic when the incident angle is defined. The intensity splitting ratio is minimum when the azimuth angle is 160°-180°.
