Quantitative measurements of flow velocity and direction using Transversal Doppler Optical Coherence Tomography

摘要

We present the first demonstration of measurements of velocity and direction of flow using Transversal Doppler Optical Coherence Tomography. The experiments are carried out using a four-channel quadrant detector at the output of a free-space Michelson interferometer. This allows real three dimensional mapping of both flow and velocity with no limitation on the Doppler angle.
