摘要：
A system of distributed optical fiber sensor has presented based on the optical fiber sensor technology and detected the oil pipeline leakage using Mach-Zehnder optical interferometer. There are two interferential signals from sensor and reference light to put in computer has been analyzed using the analysis software LabVIEW of National Instruments' that can operate for the cross-correlation function, then compare the correlation peak to obtain the disturbance of oil leakage location, the detection precision 200m at around 50km for pipeline in the high speed sampling and data signal processing has obtained.
