Recording the vortex beam parameters in turbulent atmosphere

Abstract

Based on the methods of the numerical experiments the authors study the possibility of determining the characteristics of vortex radiation expanding in turbulent medium. To obtain the estimation results given in the first part of the paper the parameters are determined using gradients of phase distribution of light field; the ideal optical system is considered.
