| 摘 要： | 光的衍射现象研究，不仅具有重要的理论意义，而且在光学仪器研制和成象分析等均有重要价值．针对衍射计算困难的问题，选择合适的计算公式，并基于科学计算软件MATLAB5．3编写计算程序，使计算得变得简洁，大大提高了实验的效率．用MATLAB编程得出的计算结果与用数码相机记录的衍射图样进行比较，两者吻合得很好．

| Abstract: | The calculation of diffraction was too complicated to be done until computer was invented. By choosing proper formula and software, not only can the result of calculation of diffraction be given, but also figures can be worked out easily. It greatly improves the efficiency of experiments. At the same time, since digital camera is more and more popularized, it provides a new method for recording diffraction pattern. It turns out to be that the results gotten by using software MATLAB 5.3 are identical with photographs taken by digital camera. |
