Laser Doppler anemometer’s noise resulting from parasitic scattering

The area boundaries of laser radiation parasitic scattering on photodetector aperture of thelaser Doppler anemometer are found. The corresponding expressions for signal-tonoise ratio are derived, which are confirmed by experiment.
