Abstract
A vibrometer system for determining the vibration spectrum of an object under examination. The vibrometer includes a bundle of optical fibers arranged in an array, wherein a majority of the fibers in the array are arranged to receive light reflected from the object under examination and a minority of the fibers in the array are arranged to transmit light to illuminate the object under examination, wherein the light reflected from the object under test by received by the majority of fibers was transmitted by the minority of fibers; a plurality of light amplifiers and detectors for amplifying and detecting the received light; and a coherent detector responsive to the detected light and to the transmitted light for providing an output signal representative of the vibration spectrum of the object under examination.
