摘要：

This article considers the processes of light propagation and scattering in biological tissues. The results obtained made it possible to estimate basic signal parameters and their dependence on various optical parameters with respect to the laser Doppler flowmeter and laser Doppler microscope. We also developed a new method to determine the indicatrix asymmetry of single and multiple light scattering by a suspension of oriented spheroidal particles that simulated erythrocytes in a shear flow. It was found that the angular dependence of the asymmetry index provides information on the shape and orientation of particles. In addition, we obtained single scattering indicatrices, which may improve the accuracy of computer simulation of light scattering by blood.
