Paper Abstract

To study biological objects such as unicellular algae, blood cells, etc., light scattering methods have been widely used."2 Many of them are based on the analysis of the changes in the coherent properties of the optical radiation. Among them are Doppler spectroscopy, the method of self-excited oscillations,2 etc. Such methods cannot however be used to study slow processes in the media with correlation times in excess of several seconds. Thus there is a need in developing new approaches to the problem of optical characterization of disperse media.3 The present paper demonstrates the possibility of determining the size distribution function of light scattering particles and evaluating their concentrations by measuring the transverse coherence function of the scattered radiation in the particle image plane, or by holographic evaluation of the Doppler broadening of the scattered radiation spectrum.
