摘　　要：根据惠更斯-菲涅尔原理,应用MATLAB软件编程,模拟了双矩孔夫琅禾费衍射的图样分布,通过改变双矩孔的大小、形状和位置等参数,观察到双矩孔衍射图样的相应变化,并得到了其特例的光强分布,这与光学理论相符合。从数值分析结果可以看出,该研究结果对于实验验证和计算较为复杂的双矩孔夫琅禾费衍射现象,具有重要的理论参考意义。Based on the Huygens-Fresnel principle,the twin rectangle aperture＇s Fraunhofer diffraction pattern is simulated using MATLAB program. The diffraction fringes change by adjusting the parameters such as square hole＇s size,the shape and position etc.,the intensity distributions of light was obtained at some special condition. These results agree with optical theory. The program can be served as a useful and significant tool to study the complicated phenomenon of twin rectangular aperture Fraunhofer diffraction.
