• Blood flow velocity depends on the size and type of blood vessel. If the distribution of the blood flow velocity in a tissue can be measured, the vascular structure may be estimated. The dynamic light scattering method allows us to measure the flow velocity and the number density of moving erythrocytes by analyzing the power spectrum of the light scattered from a tissue. To estimate the vascular structure, the regression analysis method was applied to separate the power spectrum resulting from different flow velocities. The theoretical model was verified by experimental results using a tissue blood flow model system. The results show that two velocities may be measured separately if there is a large difference between them. The cutaneous blood flow of a finger and a forearm was analyzed and compared using the proposed method.
