摘要: 为了研究单元式偏光分束棱镜分束角和光强分束比与棱镜结构的关系,采用从理论上分析o光、e光的分束角和光强分束比与光轴取向、棱镜结构角及入射角的关系,并从实验上测量分束角和光强分束比随入射角变化的方法,进行了理论分析和实验验证,取得了分束角和光强分束比随光轴取向、棱镜结构角及入射角的变化关系的数学表达式,并得到了二者随入射角变化的实验数据。结果表明,在误差所允许的范围内,实验所测的光强分束比和分束角随入射角的变化与理论计算是一致的,且分束角的变化约为入射角的1/2。Abstract: In order to study the splitting angle and light intensity splitting ratio changing with the structure of a single-element polarized beam splitting prism,at first how the o light and e light changing with the orientation of principal axis,the structure angle of the prism and the incident angle was analyzed theoretically.Then how the splitting angle and light intensity splitting ratio changing with different incident angles was measured experimentally.The mathematical expression of the splitting angle and light intensity splitting ratio changing with the orientation of principal axis,the structure angle of prism and the incident angle was deduced,and the experimental data of the splitting angle and light intensity splitting ratio changing with the incident angle were obtained.The results indicate: The tested result is well concordant with the theoretical calculation,and the splitting angle is about 1/2 of the incident angle.
