圆孔菲涅耳衍射的蒙特卡罗数值模拟

Numerical simulation of Fresnel diffraction of circular aperture using Monte Carlo method

  • 摘要: 基于惠更斯-菲涅耳原理,运用蒙特卡罗方法,采用matlab编程实现圆孔的菲涅耳衍射数值模拟,得到了平面波经过圆孔的衍射图样和光强分布曲线,与理论计算结果有较好的一致性,为深入理解光的衍射现象提供了直观形象的物理图景.

     

    Abstract: Based on the Huygens-Fresnel principle,we use Monte Carlo method to numerically simulate Fresnel diffraction of circular aperture by Matlab program.We presented a series of Fresnel diffraction patterns.All of these patterns are consistent with theoretical results by Lai.This simulation can provide a reference for better understanding of Fresnel diffraction.
