【Abstract】 A distributed optical fiber oil-sensitive sensor based on Brillouin light scattering was developed,and small-scale oil leakage can be found using it. It can be used mainly for the real-time monitoring of the small-scale oil leakage of long-distance oil pipeline,oil depots and other places. Optical fiber is embedded in oil sensitive material and laid along the simulated oil pipeline,and oil leakage can be quickly found and located by real-time monitoring Brillouin frequency shift in optical fiber using Brillouin optical time-domain analyzer(BOTDA). Experimental results show that the technology is feasible,small-scale oil leakage can accurately be located in 20 minutes.更多还原
