Strong scintillations of laser radiation in the turbulent atmosphere with rain or snow

摘要

Statistical values of intensity of laser beams propagating in the turbulent atmosphere with precipitation are discussed. Regimes of weak and strong scintillation are determined. The phenomena of saturation and of decrease of the scintillation index in the strong scintillation regime are experimentally observed and theoretically explained. Dependence of the statistical values on the geometry of experiments is investigated too. Some methods of retrieval of the atmospheric parameters are proposed.
