Abstract

The theoretical investigation of the processes of strongly focused Gaussian beams diffraction in blood capillaries with a diameter a bit greater than the erythrocyte size have been carried out. Spatial-temporal correlation functions of intensity fluctuations in dynamic statistically inhomogeneous speckles have been studied. Modified speckle-interferometrical method using strongly focused Gaussian beam scattering is suggested for blood flow measurements. The possibilities of this method application to blood and lymph flow velocity monitoring in narrow vessels has been analyzed.
