Computer-Generated Holograms change the wavefront and mode of lasers

以变换椭圆高斯光束为圆对称高斯光束为例,本文给出了用计算机制全息图作为变换元件改造激光波面和模式的理论和方法.推导出产生计算机制全息图的数学方程.制作出计算机制全息图,并得出了实验结果.

Taking that elliptical Gaussian beam change into circular symmetrial Gaussian beam as an example, this paper gives the theory and method using Computer-Generated Holograms to change the wavefront and mode of lasers, and deduces the equation of Computer-Generated Holograms. The Computer-Generated Holograms are made. Experiment results are presented.
