Abstract

In this paper the coherent properties of the vortex Bessel optical beams propagating in turbulent atmosphere are investigated. The approach to the analysis of this problem is based on the solution of the equation for the second-order transverse mutual coherence function of a field of optical radiation. The behavior of integral scale of coherence degree of vortex Bessel optical beams depending on parameters of a beam and characteristics of turbulent atmosphere is particularly considered. It is shown, that the integral scale of coherence degree of a vortex Bessel optical beam essentially depends on value of a topological charge of a vortex beam. With increase in a topological charge of a vortex Bessel optical beam the value of integral scale of coherence degree of a vortex Bessel optical beam decreases.
