Abstract
Theoretical research of coherent properties of the vortex conic waves propagating in turbulent atmosphere is developed. For the analysis of the analytical solution of the equation for the transverse second-order mutual coherence function of a field of optical radiation was used. The coherence radius, the normalized root-mean-square and the integral scales of a coherence degree of the vortex conic waves were considered, their dependence on parameters of optical radiation and turbulent atmosphere is analyzed. In particular, with increase in a topological charge the value of integral scale of coherence degree of a vortex conic wave beam are decreased. Preference of use for the adaptive optical systems compensating distortions of pseudo-Bessel beams in turbulent atmosphere as the gauge of distortions not a coherence radius measuring instrument such beam and a measuring instrument of integral scale of coherence degree is proved.
