Direction Fluctuation of Laser Beam Propagation in Turbulent Atmosphere

摘要

The formula of arrival angles of spatially partial coherent light beamspropagating through turbulent atmosphere is derived from Markovian process approximation, which can be used in both weak and strong intensity fluctuations. We also, have derived the beam wander angle and arrival angle fluctuation variance of the light beam reflected by a mirror when the beam propagating through the turbulent atmosphere. The reflecting 'amplification' characteristics of the beam wander angle and the arrival angles of light beams propagating along a folded path is discussed, which passes the distance twice between the transmitter-receiver and the mirror reflector in weak and strong intensity fluctuations.
