An SLV measures velocities of a vibrating surface by measuring the change in frequency of a laser beam reflected from the moving surface. Physically different from the electro-mechanical principles of accelerometers, the SLV offers non-contact measurements, a finer velocity resolution, a wider operating dynamic range, and higher linearity in a fully automated scanning package with ultra-high optical sensitivity.
