类圆环的夫琅和费衍射

Fraunhofer-diffraction of the Similar Circular Ring

  • 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.

     

    Abstract: 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.
