摘要
分析了具有相同结构角的两个渥拉斯顿棱镜在不同方式组合下的光路特性。给出了分束角与结构角的关系表达式,同时也给出了分束角与结构角的关系曲线。使用He Ne激光器(波长λ=633nm)对两个结构角S=27°的渥拉斯顿棱镜在四种不同组合方式下的光路进行了测试。结果表明,测试结果与理论计算完全相符。
The optical path character of Wallaston prisms that have the same structure angle in the diversity compound mode is analysed. The relational expression of beam splitting angle and structure angle, the relational curve of beam splitting angle and structure angle are givn. The optical path character of two Wallaston prisms which structural angle is S=27° by using HeNe laser(633nm) in the diversity compound mode is tested. The result shows that testing result accords with the result of theoretical calculating.
