| 摘 要： | 提出了一种光纤布喇格光栅的铝槽封装工艺,并对铝槽封装光纤光栅传感器的应变与温度传感特性进行了实验研究和理论分析.与裸光纤光栅的测试结果比较表明,铝槽封装工艺基本不改变光纤光栅应变传感的灵敏性,但是温度灵敏度系数提高了3.5倍.经过该工艺封装的光纤光栅可以探测识别0.2 με的应变与0.02℃的温度变化.

| Abstract: | In consideration of bare optical fiber being fragility,the aluminum groove encapsulating technique for fiber Bragg grating (FBG) sensor was developed ,and then the strain and temperature sensing characteristics of the encapsulated FBG sensor were experimentally and theoretically studied. The comparison of results between encapsulated FBG sensor and bare FBG sensor indicted that the strain sensing property of the FBG sensor are nearly same as that of bare FBG,however the temperature sensing ability of encapsulated FBG sensor is improved and the sensitivity coefficient is 3.5 times as much as that of bare FBG. The strain and temperature sensing resolution of the encapsulated FBG sensor are 0.2 με and 0.02℃,respectively. The encapsulated FBG is proper for application in civil engineering. |
