Abstract:

Distributed fiber sensors based on phase-sensitive optical time domain reflectometer (Φ-OTDR) show great potential applications in the field of perimeter security intrusion and structural health monitoring.This paper reviews the principle of Φ-OTDR for sensing,and the recent development of Φ-OTDR in aspects of light source,sensing head,detection method,multiplexing technology and signal processing.

Key words:phase-sensitive optical time domain reflectometer;coherent detection;frequency-division multiplexing;pattern recognition
