Abstract

There are well known factors which provoke image distortions during the propagation of light in the atmosphere. We used the solution of the linear unsteady 3D Navier - Stokes equations in order to model turbulent fluctuations of the refractive index. Parabolic equation method has been used for the solution of the problem of laser propagation. Density distribution and structure function were determined as well as their temporal evolution. Distortions of the Gaussian beam due to the fluctuations of the refractive index are presented.
