说明：  基于角谱理论艾里光束的传播,该MATLAB程序，大体上模拟出了Airy光束的二维光强分布，并在此基础上利用角谱理论，编写出了其在二维平面内的传播，只需改变其中的参数就可以展示Airy光束的移动。在此基础上加上障碍物，可以得到Airy光束的自愈合特性等特殊性质
(The matlab program, in general, simulates the two-dimensional light intensity distribution of Airy beam, and on this basis, using the angle spectrum theory, compiles its propagation in the two-dimensional plane, only changing the parameters can show the movement of Airy beam. On this basis, the self-healing properties of Airy beams can be obtained by adding obstacles)
