Paper Abstract

In this work we used angle-resolved Monte-Carlo simulation to study light propagation in non-aggregated RBC suspensions. In our model we used phase functions, calculated in different optic approximation (geometrical optics, Fraunhofer diffraction, hybrid approximation, Mie theory) as well Heyney-Greenstein function. Scattering indicatrices obtained in different approximations were compared. Heyney-Greenstein function was used for calculations at different hematocrits. It was shown that for hematocrits in a range of 20...50 % the scattering indicatrices for wavelength 633 nm do not differ significantly, however this difference is higher fro smaller hematocrit. We also compared contributions of single and multiple scattering to light intensity distribution at different angles. We showed that for 100-μm thick suspension layer the major contribution to forward scattering is given by snake-photons, while to backward scattering - by multiply scattered photons.
