Abstract :
A temperature-stabilized fiber-Bragg-grating (FBG) vibration sensor consisting of a broad-spectrum light and two FBGs (one is for sensing and other for an optical source) is examined. Keeping the temperature of the two FBGs same, the temperature-change-induced fluctuation of the sensor output is reduced down to 3dB, which is more than 55 dB without the stabilization.
