Spatial profiles of statistical moments for collimated laser beams at the end of long atmospheric path

摘要

The results of the experimental and theoretical analysis of spatial statistical characteristics of laser beams with wavefront control are presented. The experimental data obtained in different meteorological conditions is used to estimate features of spatial localization of averaged over the ensemble recorded intensity distributions and profiles of second, third and fourth spatial m oments. Registered dependence between transverse or longitudinal components of scintillation index and meteorological conditions or setting of beam forming optical system is discussed. In addition, we proposed interpretation of spatial properties of high-order central moments.
