Abstract

A novel distributed fiber-optic sensor based on Phase Generated Carrier (PGC) for determining the position of multiple disturbances is presented. The configuration and operating principle of the system is illustrated, the location principle and method for the detection system are analyzed. The system realizes the location of the multiple disturbances using the PGC demodulation technology. Theory analysis and experiment result show that the proposed technology can realize the detection and location of the multipoint disturb signals rapidly and effectively, this method is simply and can be obtained easily, it could increase the length of fiber-optic sensors which has high measurement sensitivity and location precision.
