Abstract

A four-beam two-focus differential laser velocimetry system with an acousto-optic modulator, which is suitable for measuring solid deformation or movement at ultralow speed, is presented. The signal-to-noise ratio is good enough for phase discrimination, the frequency response range is 0 to 20 kHz, and the measurable velocity range is 0.001 m/s to 300 mm/s.
