数字全息模拟软件，用菲涅尔衍射还原全息图得到原来的图像-Digital holographic simulation software, using the the Fresnel diffraction restore hologram original image

用角谱法计算菲涅尔衍射图样，计算出后加上GS算法即可得出全息图-Fresnel diffraction pattern is calculated using the angular spectrum method, after adding GS algorithm to calculate the hologram can be derived

光学重建全息图的计算机形式，菲涅尔衍射，傅里叶透镜，菲涅尔衍射-simulating the optical reconstruction of hologram pattern
