A distributed optical fiber vibration sensor based on Sagnac interferometer is developed in this paper, and it is used to detect pipeline leakage in real-time. The Principle of sensor and phase modulation theory of light are discussed. A simulation experiment is designed to verify the distributed optical fiber vibration sensor, the results verify that the detection technology can effectively detect vibrating signals.
