代码说明:

这段代码读取图像。然后计算 fft 的图像。然后首先删除振幅信息的 fft 计算 ifft 和第二删除 fft 相位信息计算 ifft。这段代码很有用可视化振幅和相位的快速傅里叶变换的图像内容。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    本程序基于Matlab,可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光,点光源任意角度光线,并对全反射,光线射出系统等特殊情况用红色标出。透镜数任意,透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)
