Abstract

We describe a technique that uses the Doppler optical coherence tomography to estimate accurately the scattering fluid-flow velocity without a priori knowledge of the Doppler angle. It is based on the combined use of the Doppler shift on interference signal and the Doppler spectrum broadening due to the moving particles across probe beam. It is shown that the estimated values of Doppler angle and average fluid velocity from the experiments agree well with the preset ones
