Abstract

New method of intensity calculation of multiple light scattering by suspensions of large nonspherical particles is developed on the basis of geometrical optics approximation. As an example of application of the method the calculation of light scattering by a suspension of aggregating particles modeling the kinetics of erythrocyte aggregation in whole blood is executed. The size of aggregates changes in the aggregation process. Light scattering indicatrices for deformable particles moving in shear flow are calculated. Theoretical explanation of experimentally observed phenomenon of light scattering asymmetry is given by analyzing the shapes of scattering indicatrices, and the theoretical time dependence of the backscattered intensity is obtained.
