| 摘 要： | 为了设计一种单元结构的反射型等分束角偏光棱镜,根据各向异性晶体中光的全反射理论及实际使用要求,从理论上对这种单元反射型棱镜的结构进行了分析,找到了一个使棱镜实现等角分束的结构角,并以此结构角为基础,分析得到了棱镜的分束角不对称度随光波入射角及入射波长的变化关系。结果表明,利用此理论结果设计的反元结构反射型偏光镜,其分束角不对称度随入射角和入射波长的变化不大,满足使用要求。

| Abstract: | In order to design a modular structural reflected polarizing prism which has an equal splitting angle,the construction of the prism was analyzed in theory by combining the reflecting principle in anisotropic crystal and practical application,and a structure angle was found which can make the splitting angle equal.Based on the angle,two aspects of the prism were calculated,i.e.the relationship between the degree of asymmetry and the incidence angle of light wave,and the relationship between the degree of asy... |
