正交双棱镜实现多光束干涉

Interference of multi-beams realized by two orthogonal biprisms

利用2个相互平行正交放置的菲涅耳双棱镜,实现空间分波阵面的四光束干涉.用Mathlab软件对实验进行仿真模拟,计算机模拟的光强分布图与实验所得的光强分布图照片符合较好.

Division-of-wave-front interference of four light beams is realized by using two orthogonal biprisms. The experimental results show good interference patterns of four light beams, which are consistent with those from computer simulation using Matlab.
