<p>An interferometric sensor includes a broadband optical source, a depolarizer for depolarizing optical radiation emitted by the broadband optical source, a matched interferometer, a sensing interferometer, and a detector. The matched interferometer contains a phase modulator. The sensor is configured so that the optical path length difference in the sensing interferometer is approximately equal to the optical path length difference in the matched interferometer.</p> |
