摘要
根据惠更斯-菲涅耳原理,运用蒙特卡罗方法,采用Matlab编程实现平面波的菲涅耳衍射数值模拟,得到了平面波经小圆孔、方孔和三角孔的菲涅耳衍射在轴上的光强分布曲线.从数值模拟结果可以直观而明确地到光强在轴上极值位置、大小等特点,能较好地实现对菲涅耳衍射的实验仿真,为深入理解光的衍射现象提供了参考.
Based on the Huygens-Fresnel principle,use Monte Carlo method to numerically simulate Fresnel diffraction of planar wave by Matlab program.When plane wave go through a little circular aperture,a little square aperture or a little equilateral triangle aperture,the axial light intensity distribution of Fresnel diffraction are obtained.By observing the result of numerical simulation,can very clearly and easily confirm the position of extremum and the light intensity.The simulation can provide a reference for better understanding of Fresnel diffraction.
