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
6
0℃ by water heated method.According to the tested data
the temperature sensitivity of the packaged FBG is 34.0pm/℃
