Abstract
The background theory of backscatter modulation and velocimetry using laser diodes is presented together with an experimental demonstration of the application of these laser diodes in laser Doppler velocimetry (LDV). The sensitivity of the laser diode system to backscatter from a diffusely reflecting target is greater than -60 dB. Tests of an LDV system using a moving air mass as the target are described. Possible applications of these systems include airspeed measurements, collision avoidance, and tracking distant objects.
