Long-Range Distributed Vibration Sensing Based on Phase Extraction From Phase-Sensitive OTDR
Distributed fiber-optic vibration sensors based on phase-sensitive optical timedomain reflectometry (Φ-OTDR) have found many applications in various fields. In this paper, we analyze the phase noise of Φ-OTDR, which is the main limiting factor of the measurement range. We found...
