基于Mathematica的简单孔径夫琅禾费衍射模拟
MATHEMATICA BASED SIMULATIONS OF SIMPLE APERTURE’S FRAUNHOFER DIFFRACTION
夫琅禾费衍射，又称为远场衍射，是指光源和观察幕离障碍物（孔或屏）均为无穷远的衍射现象，是信息光学的重要组成部分。在本文中我们利用Mathematica软件模拟分析了矩形孔径、圆形孔径的夫琅禾费衍射。利用Mathematica软件中的有关函数可灵活调节入射波长、传播距离、孔径宽度等变量，直观形象地展示各个变量对衍射图样的影响。
Fraunhofer Diffraction, which is an important part of information optics, is also known as far-field diffraction. Essentially it represents the electromagnetic field produced by an aperture at a very large distance from the aperture. The Fraunhofer diffraction of rectangular aperture and circular aperture is simulated by Mathematica ．It’s convenient to adjust the incident wave length，propagation distance and aperture’s size by means of Manipulate function to see their influence on diffraction pattern．
