菲涅尔衍射。仿真圆形光圈的菲涅耳衍射，显示菲涅耳衍射图样的模值。-Fresnel diffraction simulation of circular aperture Fresnel diffraction, display mode value of the Fresnel diffraction pattern.

单色点源圆孔衍射的数值模拟实验,很实用哦，大家可以参考一下-Monochromatic point source circular aperture diffraction simulation experiment, very practical, oh, we can refer to
