摘要

本文引入二维分形函数描述媒质折射率的起伏，研究分形相位屏对平面波的衍射问题．运用广义菲涅尔─—惠更斯原理，我们获得了通过二维分形相位屏后在Fresnel区和Fraunhofer区的衍射场及平均衍射强度分布．结果表明，分维及有关分形描述量控制着衍射强度分布．

Abstract

Two-dimensional fractal function is used to model the fluctuation of the medium refractive in dex.The diffraction of plane wave by fractal phase screens is considered.Using Fresnel-Huygens principle

the diffracted field is obtained and the distribution of average diffracted intensity is calculated.The results show that fractal dimension and other descriptors of fractal phase screen control the distribution of diffracted intensity.
