Degradation Of Laser Radar Doppler Signals By Fast Scanning Mirrors

This paper discusses the influence of fast scanning motions on the performance of laser Doppler radars and presents some experimental results obtained with a CO2 homo-dyne system. The experiments show in which way the signal returns from a moving reference target (a rotating disc) and its stationary surroundings depend on the angular frequency of a fast rotating mirror slewing the laser beam around.
