【Abstract】 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.更多还原
