衍射和干射现象的计算机仿真

Computer Simulation of Diffraction and Interference

文章讨论了对衍射和干射现象进行计算机仿真的方法，包括如何进行强度计算，如何再现具有真实感的彩色的衍射和干射图案。用 Visual C＋＋ 6.0编程，实现了任意设计衍射屏，以及对可见光范围内任意单色点光源或平面波经过衍射屏后的衍射和干射现象进行仿真。也可以计算指定点处光强和波长之间的关系。

The method of how to simulate the phenomenon of diffraction and interference is discussed, include how to calculate the intensity of the diffraction and interference pattern, and how to display the color pattern realistically. Using Visual C＋＋ 6.0,a program is developed to design diffraction screen at random, and to simulate the pattern on receive screen when using point light or plane light source under any wavelength within the range of visible light. In addition, one can use it to calculate the intensities of every wavelength at any position.
