摘要
本文在对闪烁概率密度函数进行对数变换的基础上,研究了激光大气闪烁孔径平滑因子及相关现象,并给出了传输图象的信息量.
When image plane speckle intensity integrated ovcr a finite aperture is submitted to a logarithmic transformation,the noise becomes additive and singal indepentent.The aperture average of optical scintillations and related phenomenon,and information con- tent of images of laser beam in the turbulent atmosphere are studied in our paper.
