Abstract

There are well-known factors which provoke image distortions during the propagation of light in the atmosphere. We used the solution of the linearized unsteady 3D Navier-Stokes equations in order to model turbulent fluctuations of the refractive index.This fact may be used for the construction of point spread function (PSF) for turbulent distortions. It was found that there exists a range of natural frequency for turbulent fluctuations. Structure function and correlation function were determined as well as their temporal evolution. A large amount of numerical results is presented.
