摘　　要：为了研究正八边形小孔的衍射场,首先根据惠更斯-菲涅耳原理及位移-相移定理对正八边形小孔的衍射场进行分析,得出正八边形小孔的衍射在像面上的振幅分布公式和光强分布公式,然后利用MATLAB的可视化得出正八边形小孔在像面上的衍射图样及衍射规律。In order to study the diffraction field of the octagonal hole, the diffraction field of theoctagonal hole is analyzed based on Huygens Fresnel principle and the displacement phase shifttheorem, and the amplitude distribution formula and light intensity distribution formula for thediffraction of octagonal holes on the image plane are obtained. Then the diffraction pattern anddiffraction law of the octagonal hole on the image plane are obtained by using the visualizationof MATLAB.
