摘要

我们提出了基于光纤光栅的光纤传感器，用于检测石油和天然气运输系统中的管道泄漏。在管道的每一端放置传感器，通过相关分析、时差和表面波特性的一系列计算，可以检测到管道泄漏的速度和位置。通过提高光纤光栅应变响应灵敏度，提高了光纤光栅传感器的灵敏度和定位精度。

Strain Sensitizing of High-Sensitivity SAW Sensor Based on FBG

We propose FBG (fiber Bragg grating) based optical fiber sensors for detecting pipeline leakage in oil and gas transportation systems. By placing a sensor on each end of a pipe, the velocity and position of the pipeline leakage can be detected through a series of calculations on the correlation analysis, the time difference, and the characteristics of surface waves. We improve the sensitivity and the accuracy of positioning for the FBG based optical fiber sensors by enhancing the FBG strain response sensitivity.
