摘要
应变和温度变化都会引起光纤Bragg光栅(FBG)反射波长的移动,这种交叉敏感问题是制约FBG传感检测技术实用化的"瓶颈".从应变、温度交叉敏感的物理机制出发,分两类综述国内外关于交叉敏感问题的解决方案,介绍各类方案的工作原理,并详细分析几种近年来出现的典型方案的优缺点.
Abstract
The variations of strain and temperature can result in the reflecting wavelength shift of the fiber Bragg grating (FBG), and such a socalled cross sensitivity is a "bottleneck" that limits the FBG sensing and measuring technique to put into practical applications. Two classes of the soultions to the cross sensitivity,presented at home and abroad,are reviewed from the point of view of the physical mechanisms of the strain and temperature crosssensitivity.The operating principles of each class of the solutions are described briefly;the advantages and disadvantages of some typical schemes proposed in recent years are analyzed in detail.
