Abstract
In this article, the characteristic features of formation of the Bessel optical beam in a turbulent atmosphere are analyzed. The problem analysis is based on the solution of the equation for the mutual coherence function (the second-order field moment) of a Bessel beam of optical radiation. The behavior of the spatial coherence radius of a Bessel optical beam depending on parameters of a beam and characteristics of the turbulent atmosphere is examined. It has appeared, that at low levels of fluctuations in a turbulent atmosphere the spatial coherence radius of a Bessel optical beam is larger than the spatial coherence radius of a plane optical wave, but it is smaller than the spatial coherence radius of a spherical wave. At high levels of fluctuations in a turbulent atmosphere, the spatial coherence radius of a Bessel beam becomes closer to the similar characteristic of a spherical wave.
