这个程序实现了菲涅尔衍射计算，对各种图像都课进行衍射计算，也也是全息照片重现。-Implementation of this process the calculation of Fresnel diffraction of a variety of classes for the diffraction images are calculated, it is also a hologram to reproduce photographs.

矩形孔菲涅尔衍射图像得计算程序，读者可以修改相关参数，以观察不同形式得菲涅尔衍射图像。-Rectangular aperture Fresnel diffraction image obtained calculation program, readers can modify the relevant parameters to observe the different forms have Fresnel diffraction image.

几种干涉，衍射仿真程序，包括夫琅禾费衍射，菲涅尔衍射，单缝衍射，等厚干涉，光栅衍射等-Several interference, diffraction simulation program, including Fraunhofer diffraction, Finel diffraction, single slit diffraction, equal thickness interference, grating diffraction, etc.
