| 摘 要： | 应变和温度变化都会引起光纤Bragg光栅（FBG）反射波长的漂移,即所谓的交叉敏感问题,它是制约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,阐述了光纤光栅温度补偿的基本原理,介绍了几种国内外常用的光纤光栅无源温度补偿的方法,并详细分析了每种方法的优缺点.

| Abstract: | The reflecting wavelength shift of the fiber Bragg grating(FBG) can be caused by the variations of strain and temperature,and such a so-called cross sensitivity is a "bottle-neck"which limits the application of the FBG measuring technique.The basic theory of temperature compensation of fiber Bragg gratings is presented.Several solutions about powerless temperature compensation of fiber Bragg gratings are introduced according to the physical mechanisms of the strain and temperature cross-sensitivity;the advantages and disadvantages of some schemes are analyzed in detail. |

| Keywords: | fiber Bragg grating(FBG) cross sensitivity temperature compensation |
