RANGING MICHELSON INTERFEROMETRIC SENSOR WITH COMPOUND TERMINATION

摘要

There is provided several configurations of a ranging Michelson interferometric sensor having two single made waveguides, such as optical fibers, acting as a sense arm and a reference arm. Both fibers are connected to an interferometric splitter/combiner at a first end. Each of the fibers is terminated at a second end by a compound termination. Each compound termination consists of two FRMs coupled to the corresponding fiber, one by a delay line. A detection zone for the sensor is defined to extend substantially between the interferometric splitter/combiner and the compound terminations.
