Abstract	Laser Doppler Velocimetry (LDV) has been widely used for many years in fluid mechanics to measure particle velocity. However in most applications, in industrial processes for example, such a system is often too expensive. This paper discusses a technique based on the use of an analog phased-locked loop and an analog integrator system for processing LDV data to infer particle velocity. This method appears to be suitable for designing low-cost integrated LDV sensors. A SIMULINK/sup /spl reg// program has been written in order to validate the method for velocities in the 10 mm/s to 80 mm/s range. Finally, the performance of the estimator is illustrated by Monte-Carlo simulations obtained from a synthesized Doppler signal.
