摘要：

Formation of speckled speckles in the case of biflow perfusion by partially coherent light was considered. Dependencies of statistical characteristics of low-coherence biospeckles with a small number of scatterers on the scattering properties of the how and on the coherence length of incident light were analyzed. It was shown that the value of the Doppler bandwidth in the scattered light essentially depends on the ratio between the coherence length and the average size of the dow's inhomogeneities. A procedure for reconstructing velocity distribution in a single blood vessel was suggested. (C) 2000 Optical Society of America. OCIS codes: 170.0170, 290.0290.
