Paper Abstract

The effect of multiple scattering on the validity of the Beer-Lambert law is discussed for a wide range of particle size parameters and optical depths. To predict the amount of received radiant power, appropriate correction terms are introduced. For particles larger than or comparable to the wavelength of radiation the small-angle approximation is adequate, whereas for small densely packed particles the diffusion theory is advantageously employed. These two approaches are used in the context of the problem of laser beam propagation in a dense aerosol medium. In addition, preliminary results obtained by using a two-dimensional finite element discrete-ordinates transport code are described. Multiple scattering effects for laser propagation in fog, cloud, rain and aerosol cloud are modeled.
