Laser multibeam differential interferometric sensor and methods for vibration imaging

A sensor for a vibration imaging system is provided. The sensor includes a transmitter configured to project an array of laser beams onto a surface of an object such that neighboring beams in the array of laser beams are frequency shifted relative to each other, an interferometer configured to mix r...
