摘要
光纤布拉格光栅(FBG)压力传感器具有水下无源、耐腐蚀、重量轻、成本低和抗电磁干扰等优点,应用广泛.文章简要介绍了FBG压力传感的基本原理,概述了FBG的写制技术、压力传感及增敏技术、温度补偿技术的发展现状,总结了近几年FBG压力传感器在海洋深度、湖泊液位测量、油气管道压力测量和岩土压力监测领域的应用进展,最后对FBG压力传感技术进行了展望.
Abstract
Fiber Bragg Grating(FBG)pressure sensor has the advantages of underwater passive,corrosion resistance,light weight,low cost and anti-electromagnetic interference,which has been widely used.This paper first briefly introduces the basic principle of FBG pressure sensing.It then summarizes the development status of FBG writing technology,pressure sensing and sensitizing technology,and temperature compensation technology.Next,it summarizes the application progress of FBG pressure sensor in the fields of ocean depth,lake level measurement,oil and gas pipeline pressure measurement,and rock and soil pressure monitoring in recent years.Finally,the FBG pressure sensing technology is prospected.
