随着科学技术的发展, 光学实验的计算机仿真不仅在科学与工程计算方面发挥着重要作用, 而且在光学教学方面也引起了广大教育工作者的广泛关注。Matlab软件编程实现一般是用衍射积分方法和傅里叶变换方法实现夫琅禾费衍射和菲涅耳衍射的计算机模拟。使用傅里叶变换的方法把实际光学实验现象和Matlab编程结合起来, 通过大量的对比仿真实验验证了光学衍射的规律, 在光学教学起到了一定的积极作用。

With the development of technology, optical-experiment simulations, as a novel alternative method different from theory and experiment to explore new things, are attracting more and more attention from both scientists and teachers. There are two methods for Matlab program of the Fresnel and Fraunhofer diffraction patterns, one is diffraction integration, and the other is Fourier transform. In this paper, Fourier transformation well combined optical experiment phenomena and Matlab program. And with a lot of comparison of simulation experiments optical diffractive law was verified, which will contribute positive effect to optics teaching.
