摘要
根据大气湍流的统计特性规律 ,对孔径为 1 .5m望远镜的随机相位屏的产生以及望远镜成象特性进行了模拟 .对相位屏的方差、低频特性进行了有效控制和改善 .用大气的结构函数和大气望远镜的散斑传递函数两种方法对随机相位屏的光学特性进行了评估 。
According to statistical property of atmosphere turbulence,random phase screens for simulating the optical effects of atmosphere turbulence and speckle imaging process simulation of a telescope with 1.5m aperture size are presented in this paper.And how to control phase screen parameters and improve low frequency characteristic are also described in detail.The optical properties of the random phase screens are verified by atmosphere structure function,and speckle transfer function of the atmosphere/telescope system as well.
