【摘要】 在物理光学教学中，光的衍射是其中最重要的内容之一。本文介绍了光的衍射中夫琅禾费衍射的基本原理，用Matlab软件模拟了不同孔径下夫琅禾费衍射光强的分布情况。该仿真实验简单直观，易于操作，对物理光学的课程讲授和大学物理实验的教学有很好的辅助作用。更多还原

【Abstract】 Diffraction of light is one of the most important contents in physical optics teaching.It introduces the basic principle of Fraunhofer diffraction in light diffraction,and simulates the intensity distribution of Fraunhofer diffraction under different aperture with Matlab. The simulation experiment is transparent,intuitive and easy to operate,which plays a very helpful role in the teaching of physical optics and college physics experiment.更多还原
