| Abstract: | In this paper, a model was put up to non invasively measure capillary blood flow using diffusion light auto correlation. The influences of the Brownian motion of scatterers and the capillary blood flow on the auto correlation of diffusion light were theoretically analyzed. The theoretical and Monte Carlo simulation results show that the characteristic correlation time exponentially decays as the mean square velocity of capillary blood flow increases. |

| Keywords: | auto correlation dynamic light scattering blood flow non invasive measurement |
