Paper Abstract

An analysis of laser light fluctuations may indicate a state of a bloodery. In the study spectral characteristics of a dynamic speckle field scattered by skin with different microcirculation are investigated in detail. Among them: a power of fluctuations, a ratio of spectral amplitudes for two different harmonics, an average frequency of fluctuations, a spectral width and so on. A variation of these parameters during blood flow changing are discussed. An real time algorithm is used to get a map of microcirculation.
