通过光瞳函数傅里叶变换计算 光学系统OTF-By the optical system of the Fourier transform of the pupil function OTF

程序的主要目的是获得光学传递函数，通过光程差获得光瞳函数，之后获得点扩散函数，最终得到光学传递函数。-The main purpose of the program is to obtain an optical transfer function, the pupil function obtained by the optical path difference, after obtaining the point spread f

常用光瞳函数，矩形函数、圆域函数、正六边形函数、三角形函数的绘制(Commonly used pupil function, including rectangle function, circle function, hexagon function, triangle function)
