Paper Abstract
Laser Doppler Velocimetry is used here to measure sinusoidal structural velocities. Two systems for signal acquisition and processing, one available commercially and the other being developed in our laboratory, are assessed in detail. Their performance and limitations are evaluated by means of a comparison of the estimated velocities with reference values given by a laser vibrometer. Both systems show close and satisfactory performance up to 2 kHz for rms velocities higher than 1 mm/s.
