摘　　要： 研究了光纤布拉格光栅的封装及其布设工艺,以及封装后的传感理论,提出并实现了一种光纤布拉格光栅的封装工艺,即用导热性能良好的紫铜片对光纤布拉格光栅进行封装,这种封装结构简单小巧。通过实验对裸光栅和封装后光纤布拉格光栅的温度传感特性进行了研究。研究表明:经过紫铜片封装的光纤布拉格光栅,其温度灵敏系数比裸光纤光栅的提高了2.94倍,有助于提高解调设备的温度分辨率,可以探测到0.03℃的温度变化,且重复性好;该封装结构利用了紫铜的耐腐蚀性,适用于分布式传感网络,便于工程应用。 Studied are the,packaging and embedding technique for the FBG temperature sensors, as well as their sensoring principles. Presented is the scheme of packaging technique of the FBG with a compact structure by using the red copper slice. The temperature sensor characteristics of the bare FBG and the packaged FBG were researched. The results indicate that the temperature sensitivity coefficient of the packaged FBG is 3.94 times as much as that of the bare FBG, and the packaging technique improves the temperature resolution of the demodulation equipment, being capable of measuring the change of 0.03 ℃ and owns a good repeatability. This FRG packaging structure based on the corrosion resistance of red copper for FBG can be used to build the distributed sensor network, and the FBG packaged sensor can be easily used in engineering.
