Abstract

The optical analyzing method of blood micro-circulation and another dynamical characteristics of biological objects based on using the low-frequency processing of scattering laser wave is represented. The main idea of the method proposed is the combination of adaptive virtual optical filter as a lateral diaphragm of laser speckles, formed by scattering of laser wave in a biological tissue, and a multi-segment photoreceiver in the plane of analysis. The method of speckle-interferometry allows to develop the system of express-measuring and control of the local dynamical parameters of biological objects with the sensitivity more than it is in a traditional Doppler analysis scheme.
