消除光纤光栅温度压力交叉敏感技术进展

Development of the technology of eliminating FBG's temperature and pressure cross-sensitivity

光纤光栅(FBG)的谐振波长既对环境的温度敏感,又对环境的压力敏感,也就是存在温度压力交叉敏感问题。文章从光纤光栅温度与压力交叉敏感问题的物理成因出发,针对单一参量(温度或压力)和双参量(温度与压力)FBG传感器的交叉敏感问题,分三类阐述交叉敏感问题消除方法的最新进展情况。

Based on the physical reason of the FBG＇s temperature and pressure cross-sensitivity problem, this article mainly talks about the latest development of three sorts of ways to eliminate temprerature and pressure cross-sensitivity issue which exists in single parameter （temperature or pressure） and double parameters （temperature and pressure） FBG sensor.
