• Abstract:
  The TSC Laser Doppler Velocimeter (LDV) senses air movement by measurement of the Doppler frequency shift of laser radiation backscattered by the atmospheric aerosol. The TSC LDV system possesses instrumentation to transmit the laser radiation to the region of interest, collect the radiation scattered from the atmospheric aerosol, and to photomix on a photodetector the scattered radiation and a portion of the transmitted beam. The difference between the transmitted frequency and the returned frequency is the Doppler shift frequency. The Doppler frequency shift signal is generated at the photo­detector and is directly proportional to the magnitude of the wind velocity component in the direction of the line of sight of the laser beam. This ve­locity component is hereafter called the line-of-sight velocity, and it is the basis for most VAD calculations.
