摘要
在衍射理论基础上.通过对衍射公式以及光波通过透镜后所引起的相位变化的讨论.提出了利用FFT模拟光学系统的计算机算法.并给出了模拟结果.
Based on diffraction theory, this paper discusses the diffraction formulas and the phase change brought about by the light which passes through a lens. A computer algorithm that uses FFT to simulate the optics system is presented, and the results of the simulation are given. It would be important for design of coherent optical systems.
