Paper Abstract

A method of flow direction and velocity determination using statistical properties of dynamic speckles is proposed. Two point detection of scattered light intensity fluctuations allows for slow flows velocity measuring and flow direction determination without incident beam frequency shifting and with using one focused incident beam. The space-time correlation functions estimated for two position of the incident beam waist allows for the flow space localization and the absolute flow velocity measuring. The described method has the principal advantages for the bioflow investigations in comparison of the traditional laser Doppler velocimetry.
