Abstract
A laser vibrometer for measuring the vibratory characteristics of an object and more specifically, a moving object, has an improved signal to noise ratio due to multiple channels. A laser is split into a plurality of channels and then for each channel split again into a reference beam and a probe beam. The probe beam is directed at the object and the back scattered reflections are collected and compared to the reference beam to determine the vibratory characteristics of the object. The received signals from the multiple channels are different, sequential and non-overlapping.
