Solution of the problem of light scattering by ice non-spherical particles obtained in the approximations of geometric and physical optics for problems of laser radiation transfer

Abstract

The paper presents a comparison of numerical solutions for the problem of light scattering on ice particles using methods of geometric and physical optics. The solutions were developed for irregularly shaped particles ranging in size from 10 to 100 µm, with a wavelength of 0.532 µm. The results of the comparison of the light scattering matrix over the entire direction sphere indicate that the solution within the framework of geometric optics approximation is in good agreement with the solution within the framework of physical optics over the entire scattering sphere, except for the vicinity of scattering in the forward and backward directions.
