An overview of Doppler global velocimetry

OSTI ID:5443002
Doppler global velocimetry (DGV), currently undergoing development at NASA-Langley, obtains velocity measurements by identifying the Doppler frequency of laser light that is scattered by submicronic particles moving within the flow. An effort is here made to predict DGV's measurement capabilities and envision plausible applications. Attention is given to frequency discrimination, illumination and seeding nonuniformities, velocity component resolution capabilities, and attainable levels of temporal and spatial resolution. 8 refs.
