Abstract
The phase screen with different atmospheric turbulence intensities was numerically simulated by Fourier transform method. Meanwhile, the phase and light intensity distribution characteristics of the Gaussian laser beam passing through the atmospheric turbulence were numerically studied, and the theoretical results and practical conclusions of the atmospheric phase screen were verified. The results show that the phase screen produced by Fourier transform method can intuitively illustrate the phase characteristics of atmospheric turbulence, and the phase and light intensity distribution of the Gaussian laser beam passing through atmospheric turbulence of different intensities were consistent with the theoretical analysis. Numerical simulation has certain guiding significance for the engineering application of laser transmission in the atmosphere.
