LOW-COHERENCE INTERFEROMETRIC SENSOR SYSTEM UTILIZING AN INTEGRATED OPTICS CONFIGURATION

摘要

implementation of a twin Mach-Zehnder reference interferometer in an integrated optics substrate is described. From measurements of the fringe visibilities, an identification of the fringe order is attempted as a way to provide an absolute sensor for any parameter capable of modifying the difference in path length between two interfering optical paths.
