Experimental Studies of the Potentialities of Backscattering Dynamical Spectroscopy for Investigating the Characteristics of Biological Particles with Different Shape and Surface Relief

Abstract

The attempt is made to extend the applicability of dynamic spectroscopy methods, that are commmonly used to investigate media with relatively low concentrations of light scattering particles, for analyzing media with high volume content of scatters where the so-called multiple scattering regime is established. The whole blood of a person under normal and pathological state is chosen as a model medium. The dependence of characteristics of the spectrum of the temporal fluctuations of light scattered intensity on parameters of particles (the concentration, their shape, absorption coefficient, aggregation degree) is studied. It was found that the fluctuation spectrum of multiply scattered light under high concentrations of scattering particles is mainly influenced by their optical characteristics, rather than by geometrical ones.
