摘要
圆环夫琅和费衍射已有精确解 ,更一般的类圆环夫琅和费衍射精确解未见报道。本文从基尔霍夫衍射积分公式出发 ,利用曲线坐标关系和类圆傅里叶变换 ,求得类圆环夫琅和费衍射的精确解 ,作出几种典型的类圆环的夫琅和费衍射图样 ,并对其进行了分析。
The analytical result of Fraunhofer-Diffraction of the circular ring is known but that of the similar circular ring isn't. Based on Kirchhoff diffraction integral formula, the analytical result of Frauhofer-Diffraction on the similar circular ring is derived in this paper. Utilizing the relations of curve coordinate and Fourier-transform of similar circle. The diffraction patterns of the several typical similar circular rings are given and analyzed.
