Abstract：The methods of power spectrum,random midpoint displacement,linear interpolation and statistical interpolation are used to generate the atmospheric turbulence phase screen under Kolmogorov and Non-Kolmogorov turbulence models. By com?paring the frequency information of the phase screen,and the phase structure functions are compared with the theoretical results, the applicability of these four phase screen simulation methods under different turbulence models are analyzed. It shows that the fre?quency information of the phase screen generated by random midpoint displacement method under the Kolmogorov and the Non-Kol?mogorov turbulence model is sufficient and the simulation efficiency is high,the relative error between phase structure function and theoretical value is the smallest in the two models.
