Abstract

Formulas relating to diffraction of focused Gaussian beam from narrow blood microvessel have been derived. Vessel has been considered as a set of moving random screens. The correlation function of intensity fluctuations of statistically inhomogeneous speckled biospeckles has been studied with regard to flow measurement. It has been shown that the value of Doppler bandwidth in the scattering light essentially depends on the spatial velocity distribution in the blood flow.
