A SYSTEM FOR INTERROGATING AN INTERFEROMETER, AN INTERFEROMETRIC SYSTEM AND A METHOD FOR INTERROGATING AN INTERFEROMETER

摘要

Disclosed herein is a system (10) for interrogating an interferometer. The system (10) comprises an optical signals generation system (14) for concurrently generating a plurality of optical signals that each have a modulation parameter that the other of the plurality of optical signals d not have. The optical signals generation system (14) is for optically coupling each of the plurality of optical signals to a plurality of optical ports (16, 18, 20) of the interferometer (12) for ingress of the plurality of optical signals into the interferometer (12). The system (10) comprises an interferometer output processing system (22). Also disclosed herein is an interferometric system and a method for interrogating an interferometer
