Abstract

The digital speckle correlation method (DSCM) used to measure blood flow velocity is here analyzed. The experiment is designed to obtain the dynamic speckle pattern of blood which is shot by CCD. Then the DSCM is used to process the sequential images and the experiment is simulated. The experimental results show that the DSCM can measure blood flow velocity, and have a good agreement with the simulation results. [ABSTRACT FROM AUTHOR]
