Laser Doppler velocimeter as an optoelectronic data processing system.
Using Fourier optics, the conditions of the laser Doppler velocimeter (LDV) optimization in relation to the scattering center size, laser parameters, and photoreceiver aperture are found. The measurement errors are estimated for average and instantaneous velocities with regard to the statistics of the scatterers. The compensating scheme, which eliminates a low-frequency component of the signal and laser noise, is described. The results of its experimental applications are given.
