Imaging of fluid flow velocity using Doppler optical coherence tomography: preliminary results

Doppler optical coherence tomography (Doppler OCT) is a technique combining Doppler velocimetry with optical coherence tomography to measure fluid flow velocity at discrete spatial locations. Doppler OCT is an accurate method for the characterization of high resolution (<1 mm/s) fluid flow velocity. Some modifications on current OCT systems have been performed to realize Doppler OCT. Preliminary results on spatial profiles of fluid flow velocity in transparent plastic conduits are presented.
