Application of optical coherence interferometry to measure the spatial profile of fluid flow velocity
Published Web Locationhttps://doi.org/10.1117/12.221538
The spatial profile of fluid flow velocity in transparent glass conduits is measured using optical Doppler tomography (ODT). The flow velocity at any spatial location in the conduits is determined by measuring the Doppler shift of backscattered light from moving microspheres in the fluid. ODT is an accurate and inexpensive method for high resolution characterization of fluid flow velocity profile.
