摘要
从Wollaston棱镜结构出发,寻找到两种设计方案,即把出射面为平面改为两个平面,若两平面向里凹,能得到大分束角对称分布的o、e光;若两平面向外凸,能得到剪切差大的平行出射的o、e光。大大拓宽了Wollaston式棱镜的使用范围。
From the structure of Wollaston prism, two designs are sought, that i s, change one flat of the exit facet into two flats. If two flats are concave,b ig splitting angle is obtained; If two flats are convex, big shear difference is obtained. Range of Wollaston prism's use is widened.
