Computer simulation of a partially coherent laser beam backscattering in atmosphere

摘要

The results of computer simulation of backscattering of the partially coherent pulsed laser beam by atmospheric aerosol or molecular layer are present. Dependence of the mean power of backscattered radiation in the focal plane of receiving telescope on the spatial partial coherence of the laser source is investigated. Analysis is carried out for the ring-shaped transmitting aperture in cases of collimated and focused laser beam incident on scattering layer. It is shown that the mean power depends on the parameters of phase fluctuations of spatially partially coherent laser source.
