Abstract

A real-time detection and self-control phase-sensitive optical time-domain reflectometer (φ-OTDR) distributed sensor system is demonstrated. The system software can get the real-time data stream to detect the disturbance and self-control the Mach-Zehnder electro-optical modulator (MZEOM). In this way, the system can operate continuously and compensate the drift of the MZEOM automatically.
