Abstract
The spatial profiles of fluid flow velocity in transparent glass and t urbid collagen conduits are measured by optical Doppler tomography (OD T). The flow velocity at a discrete user-specified spatial location in the conduit is determined by measurement of the Doppler shift of back scattered light from microspheres suspended in the flowing fluid. Expe rimental data and theoretical calculations are in excellent agreement. ODT is an accurate method for the characterization of high-resolution fluid flow velocity.
