摘　　要：为了深入研究大气湍流对光传播的影响,以大气湍流波前畸变理论和光学成像原理为基础,利用Zernike多项式展开法进行了大气湍流畸变相位图及光强图的数值模拟,数值模拟值与残差的理论值一致。设置不同的输入参数模拟各种不同大气湍流强度下的畸变相位图、光强图和Zernike系数,在基于深度学习的自适应光学系统中进行了相关测试,获得了较好的校正效果。In order to study the influence of atmospheric turbulence light transmission,according to the theory of atmospheric turbulent wavefront aberrations and the basis of the optical imaging principle,Zernike polynomial expansion method is used to simulate the phase and intensity of atmospheric turbulence distortion,the numerical simulation value is consistent with the residual error of the theoretical value.Different input parameters are set to simulate the distorted phase diagram,light intensity diagram and Zernike coefficient under different atmospheric turbulence intensities,and relevant tests are carried out in the self-adaptive optics system based on deep learning,and good correction effects are obtained.
