基于Matlab的光学衍射实验仿真摘要
光学试验中衍射实验是非常重要的实验光的衍射是指光在传播过程中遇到障碍物时能够绕过障碍物的边缘前进的现象光的衍射现象为光的波动说提供了有力的证据衍射系统一般有光源、衍射屏和接受屏组成按照它们相互距离的大小可将衍射分为两大类一类是衍射屏与光源和接受屏的距离都是无穷远时的衍射称为夫琅禾费衍射一类是衍射屏与光源或接受屏的距离为有限远时的衍射称为菲涅尔衍射。
本文用Matlab软件对典型的衍射现象建立了数学模型，对衍射光强分布进行了编程运算，对衍射实验进行了仿真。最后创建了交互式GUI界面，用户可以通过改变输入参数模拟不同条件下的衍射条纹。
本文对于衍射概念、区别、原理及光强分布编程做了详细全面的介绍关键字：Matlab；衍射；仿真GUI界面光学实验
