摘　　要：为了研究Cantor集合光栅的衍射场,首先根据惠更斯-菲涅耳原理及位移-相移定理对Cantor集合光栅的衍射场进行研究,得出Cantor集合光栅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Cantor集合光栅在像面上的衍射图样及衍射规律。这对深入研究分形光学有重要意义。The diffraction field of Cantor set grating was studied with Huygens-Fresnel principle and displacement-phase shift theorem.The formula of diffraction amplitude distribution and light intensity distribution of Cantor set grating on the image plane were obtained.Furthermore,the diffraction pattern and diffraction law of the Cantor set grating on the image surface were visualized with MATLAB.The results may be useful in the deep study of fractal optics.
