摘要: 根据惠更斯-菲涅耳原理,利用数值计算的方法对方孔夫琅禾费衍射实验进行了模拟,在验证衍射理论的同时,还得到了非傍轴区域和微方孔的衍射图,拓展了衍射的概念,为深入理解光的衍射提供了参考.

Abstract: Based on the Huygens-Fresnel principle,the square hole Fraunhofer diffraction is simulated numerically.The theory of diffraction is verified,the diffraction patterns of non-axis space and small square hole are also obtained.This can expand the concepts of diffraction and provide a reference for better undersatnding of diffraction.

Key words: Huygens-Fresnel principle, numerical calculation, square hole Fraunhofer diffraction, MATLAB
