Abstract
A motion transducer based on coherent mixing of laser light backscattered from rough surfaces is evaluated in terms of sensitivity, bandwidth, and range. Tests made with a prototype composed of a 4-mw hene laser, a silicon avalanche photodiode, and a 15-cm-aperture telescope demonstrate that remote measurements with reasonable bandwidth and accuracy are feasible at distances up to 100 meters.
