Abstract
We demonstrate a method for measuring the total velocity components of particle flow using optical coherence tomography. When passing through a probe volume, moving particles cause the intensity variation of backscattered light. The intensity signal contains the velocity information about the particle flow. Such variation is separated into a phase modulation and an amplitude modulation, from which the axial and transverse components of velocity are obtained. The proposed method is experimentally verified using polystyrene particle suspension flow.
