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。(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.)
