摘要

研究了一种由一个广谱光和两个光纤光栅(一个用于传感，另一个用于光源)组成的温度稳定光纤布拉格光栅(FBG)振动传感器。在保持两个fbg温度相同的情况下，温度变化引起的传感器输出波动减小到3dB，而在没有稳定的情况下，传感器输出波动大于55db。

Temperature stabilization of fiber Bragg grating vibration sensor

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.
