Patent abstract

A remote mass is excited with one or more beams, and the surface vibrations of the excited mass are detected with one or more laser vibrometers. Each vibrometer generates a signal indicative of the surface vibrations which is stored, reversed in time, and applied to modulate an exciter beam that is then impinged onto the mass.
