Paper Abstract

Laser speckle technique developed for monitoring of micro scale blood and lymph flows is described and discussed. It is based on the space-time correlation properties of dynamic speckle field formed by coherent light scattered by capillary flow of blood or lymph. As it was proved experimentally, the estimating of cross-correlation of speckle-field intensity fluctuations recorded in two different point allows for measurement of flow velocity and flow direction discrimination. Developed technique was applied for investigation of push-pull dynamics of lymph flow in rat mesentery. The results of experiments with models of bioflows and in vivo measurements are presented.
