| 摘 要： | 提出了一种适用于建筑结构传感的光纤光栅传感器.用细的不锈钢管匹配叠套方式保护光纤光栅,它能与建筑结构有很好的融合.这样的传感器对应力和温度响应具有良好的线性关系,其线性拟合度达0.9996和0.9985. 分段封装光纤光栅使之具有双反射峰,通过测量两反射峰的漂移能够消除温度交扰效应. |

| Abstract: | For monitoring building structure,one kind of more fitful FBG sensors is presented.The FBG is protected by a section of thin stainless steel pipe,so it is compatible with building structure.The sensor has a good linearity to stress and temperature,the correlation coefficients of fitting lines are 0.9996 and 0.9985. The FBG is divided into two parts which have different package,so it has two peaks.By measuring the shifts of two reflection peaks,the crosstalk effect of temperature can be canceled. |
| Keywords: | Building structure Grating-type fiber sensor Packaged by matched steel pipes |
