Enhanced Stability in Partial Discharge Detection: A Differential Matching Approach for Fabry-Perot Interferometric Sensors

IEEE Photonics Journal
This paper proposes a white-light path-matched differential interferometry (WL-PMDI) system combined with phase-generated carrier (PGC) demodulation for ultrasonic detection of partial discharges using extrinsic Fabry-Perot interferometric (EFPI) sensors.
