The operation of a frequency tracker for use with the laser Doppler velocimeter (LDV) is reported. Topics discussed include: laser beam profile, lens matching, and LDV resolution data. It is concluded that the LDV provides good ground wind signals. The loss in sensitivity of the cavity system at high frequencies is partly compensated by an increase in the scattering cross section of the atmosphere due to dust.
Analysis and measurement of characteristics of wide band frequency trackers and design and fabrication of all angle laser Doppler velocimeter
Laser Doppler velocimeter for measuring turbulence in gas and fluid flows
Laser Doppler velocity instrument for measuring turbulence and mean velocity in subsonic and supersonic gas flows
Three-D instrument using a laser light source measures both turbulence and mean velocity of subsonic and supersonic gas flows. This instrument is based on the measurement of the Doppler frequency shift of light waves scattered by moving particles in the gas stream.
