摘　　要：由于裸光纤本身的脆弱性问题,介绍了一种光纤光栅非金属耐腐蚀的保护性封装工艺,并通过使用恒温箱对其温度传感特性进行了研究。在35~80℃温度范围,对这种光纤Bragg光栅温度传感器的反射谱进行了测量。实验结果表明：封装的传感器获得很好的重复性并没有迟滞现象,其温度灵敏度系数为9.93 pm/℃,线性拟合度高于0.999。The nonmetal and corrosion resisting packaging technique for fiber Bragg grating（ FBG） sensor was introduced due to the fragility of bare optical fiber,and the temperature characteristics of the packaged FBG sensors were experimentally and theoretically studied in constant temperature box. Reflectance spectrum of the fiber Bragg gratings were measured in the temperature range from 35 to 80 ℃. Experimental results show that there is a preferable repeatability and almost no hysteresis effect. The temperature sensitivity of this new fiber Bragg grating temperature sensor is about 9. 93 pm / ℃,and its linear fitting is more than 0. 999.
