The program evaluates zoom lens design performance by comparing the image plane displacement and relative zoom range and it also optimizes the initial system to larger zoom range. Useful to optics students on lens courses.

光学领域，基于Matlab编写的图像生成演示程序，可生成菲涅尔衍射中的圆孔衍射图样，并进行了多个参数的模拟对比，彩色图样更加清晰。-Optics, image generation based on Matlab prepared demo program can generate Fresnel diffraction diffraction pattern of the hole and make a simulated comparison of multiple parameters,
