摘要

针对利用聚合物作为衬底材料或胶粘剂进行封装的光纤B ragg光栅（FBG）传感器在长期使用过程中出现的老化、蠕变等问题

考虑采用熔点较低的锡焊完成了1 529.0 nm FBG的全金属封装;利用水浴加热的方法在19

0℃的温度范围内

测得经封装后的FBG的温度灵敏度为34.0 pm/℃

是封装前的3.3倍

且有较好的重复性。

Abstract

Aimed at the problem of aging and changing slowly arised from long-term use of fiber Bragg grating（FBG） sensor

which is packaged by polymer or gooey

stannum is adopted which melting point is low to accomplish the packaging of 1529.0nm FBG.The experiment of the temperature characteristics on packaged FBG is carried out from 19

0℃ by water heated method.According to the tested data

the temperature sensitivity of the packaged FBG is 34.0pm/℃

which is 3.3 times as before

and has better repetition.
