衍射光学光束整形元件设计
目标：在透镜后焦面上实现图形的光强分布
实现：
1、波长、衍射光学元件口径、形状、入射波前、二维目标分布及尺寸等都可自行设定；
2、对相位进行8台阶量化，重新计算；
3、更换输出面的采样间隔，重新计算。
English Description：
Design of Diffraction Optical Beam Shaping Element Objective:To realize the intensity distribution of the pattern on the focal plane behind the lens. Realization:
1. Wavelength, aperture, shape, incident wavefront, two-dimensional target distribution and size of diffractive optical elements can be set by themselves.
2. The phase is quantized by 8 steps and recalculated.
3. Replace the sampling interval of the output surface and recalculate it.
