Paper Abstract

Coherent properties of the Bessel optical beam formed in turbulent atmosphere are studied. The problem analysis is based on the solution of the equation for the transverse second-order mutual coherence function of a field of optical radiation. The behaviour of the modulus of the normalized second-order mutual coherence function of a Bessel optical beam depending on parameter of a beam and characteristics of turbulent atmosphere is investigated. The behaviour of degree of coherence of a Bessel optical beam depending on parameter of a beam and characteristics of turbulent atmosphere is studied in details. It has appeared that at low levels of fluctuations in turbulent atmosphere the degree of coherence of a Bessel optical beam demonstrates oscillating character depending on the difference of the transverse spatial coordinate. At high levels of fluctuations in turbulent atmosphere, degree of coherence of a Bessel beam (as it is qualitative, and quantitatively) becomes closer to the similar characteristic of a spherical wave.
