| 摘 要： | 为了精确确定渥拉斯顿棱镜分束角的精度,对渥拉斯顿棱镜的分束角进行了计算,得出了其精确的分束角,给出了分束角Φ1,Φ2随结构角s的变化曲线,并对其分束角的不对称性进行了分析.结果表明,结构角较小时,渥拉斯顿棱镜的对称性非常好,随着结构角的增大,其对称性下降。

| Abstract: | In order to determine the accuracy of the Wollaston prism’s splitting angle,we carry on the computation of the Wollaston prism’s splitting angle and get precise results.We also get the relation curve between the splitting angle Φ1,Φ2 and the structure angles.Then we analyze its asymmetry.The result showed that when the structure angle is very little,the symmetry is very perfect.But when the structure angle is becoming more and more large,the asymmetry is apparent. |
