摘要
为了更好地设计和选择使用分束李普奇棱镜和分束格兰-汤普逊棱镜,从理论上分析了分束李普奇棱镜与分束格兰-汤普逊棱镜的分束角、分离角和光强分束比。结果表明,分束李普奇棱镜和分束格兰-汤普逊棱镜的分束角和光强分束比与棱镜的结构角和副结构角有关;对于相同的结构角和副结构角,两种棱镜的分束角相同,但它们的光强分束比不同。出射的o光与e′光的分离角与副结构角有关;对于o光垂直出射的需要,选用分束李普奇棱镜设计为好;对于大分束角的需要,选用分束格兰-汤普逊棱镜设计为好。选用最佳设计方案可以分别实现两种棱镜光强的对称分束,实验结果与理论计算相符。
Abstract
In order to design and use the splitting Lippich prism and the splitting Grand-Thompson prism,the splitting angle,separation angle and splitting ratio of light intensity were analyzed.The results show:the splitting angle and splitting ratio of light intensity of the splitting Lippich prism and the splitting Grand-Thompson prism are dependent on the structure angle and the vice structure angle;both the prisms have the same splitting angle and different light intensity splitting ratios if they have the same structure angle and vice structure angle.The separation angle about beam o and beam e′ is dependent on the vice structure angle:the design of splitting Lippich prism is better for the need of normal output of beam o;the design of splitting Grand-Thompson prism is better for the need of a big splitting angle.With optimum design symmetric beam splitting of light intensity can be achieved for both the prisms.The experiment data are in accordance with the theoretical results.
