Abstract
Optical Doppler tomography is demonstrated to be a simple, accurate, a nd noncontact method for measuring the fluid velocity of laminar flow in small-diameter (similar to 0.5-mm) ducts. Studies are described tha t utilize circular (square) plastic(glass) ducts infused with a moving suspension of polymer microspheres in air and buried in an optically turbid medium. The measurement of Doppler-shifted frequencies of backs cattered light from moving microspheres is used to construct a high-re solution spatial profile of fluid-flow velocity in the ducts.
