Abstract
A laser based accelerometer system uses small motion induced shifts in frequency to measure the motion of an object without contact thereof. This technique is particularly useful for determining the vibratory and velocity characteristics of objects that are otherwise inaccessible for direct motion measurement by contact sensors.
