设计二元（0-pi）型Damman光栅产生特定拓扑核的涡旋光-Design two yuan (0-pi) Damman grating to produce the particular topology Optical vortex core

这五个程序是有关涡旋光的产生和光栅生成的程序。1.是单束涡旋光生成 2.生成叉形光栅。3.生成立体的涡旋光。4.生成不同拓扑荷数涡旋光对应相位图。5.生成正弦周期光栅和螺旋相位片图(These five programs are programs for the generation of vortex beams and the generation of grating. 1. is the generation of singl

利用对数极坐标到直角坐标系的变换实现不同拓扑荷数涡旋光束的并行检测，可用于光通信，以及对涡旋光性质的理解。整个仿真基于PRL文章“Efficient Sorting of Orbital Angular Momentum States of Light”(The parallel detection of vortex beams with different topological charges is realized by usi
