Low-coherence interferometric fiber multiplexed sensor systems using an integrated optical configuration

摘要

Abstract: This paper will describe the implementation of a twin Mach-Zehnder reference interferometer in an integrated optics substrate. From measurements of the fringe visibilites an identification of the fringe order is effected, thus providing an absolute sensor for any parameter capable of modifying the difference in path length between two interfering optical paths. Such interferometers also are readily multiplexed into a quasi-distributed system. !9
