Abstract

The theoretical and experimental investigations of the focused Gaussian beam (FGB) diffraction both in blood and lymph microvessels have been carried out. Speckle-interferometrical technique with the spectral analysis of scattered light intensity fluctuations has been applied for the investigation of lymph circulation in native microvessels. The measuring errors ofbioflow velocity has been analyzed. Alterations caused by the drug influence on lymph vessels have been studiecL Doppler method using FGB scattering is considered theoretically and experimentally. Keywords: focused Gaussian beam, diffraction. speckles, correlation function. lymph flow
