Overview of Fiber Optic Pipeline Monitoring Sensors

Abstract:

This paper provides a review of fiber optic pipeline monitoring sensors development over recent decades. We analyze pipeline monitoring sensors based upon different optical techniques, such as Sagnac effect, Brillouin & Raman backscattering, fiber Bragg grating, Mach-Zehnder interference and OTDR (Rayleigh backscattering). We present theoretical principles & experimental achievements by the different techniques and analyze the advantages & weaknesses for each technique. Finally, some future research directions in this research field are discussed.
