Abstract : The use in optical sounding systems of lasers with high power and short (up to 10 to the minus 9th power/sec) duration of the emitted pulse makes possible the identification of the lower and upper boundaries and spatial inhomogeneity of diffuse clouds with a resolution not attainable in searchlight sounding. The algorithm of the Monte-Carlo method used in the present article allows one to take into account the complex boundary conditions which arise in the propagation of a diverging, spatially restricted beam of light in a scattering medium with a stratified inhomogeneity; it also allows one to take into account the nonstationary condition of the process.
