摘要

基于线性滤波器的解调法是通过探测两路光的光功率比值来确定外界温度和压力变化的。本文通过实验证明了在相同的温度或压力下，随着光源总功率减少，两路光的比值不相同，从而影响了系统的稳定性。为了提高系统的稳定性，对两路光功率的变化进行了分析，找到了背景噪声是影响两路光比值变化的基本原因，并对背景噪声进行了处理。实验结果表明，处理背景噪声后的光纤布拉格（FBG）传感器在不同的温度环境下并改变光源功率大小时，比值较恒定，系统具有很好的稳定性。该修正方法同样适用于应变和压力等实验中系统稳定性的测量。

Abstract

The demodulation based on a linear filter determines the changes of external temperatures and pressures according to the ratio of optical powers from two beams. However

this paper points out that the ratio of two beams changes with the reduction of total powers of a light source under the same state of temperature and pressure by practical experiments and it effects the system stability seriously. In order to improve the stability of the system

this paper analyzes the changes of ratio of optical power from two beams

and obtains that the background noise is the significant reason that affects the two beams ratio. Then it processes the background noise by a processed method. The experiment result shows that the Fiber Bragg Grating (FBG) sensor has a constant ratio under different temperatures and changed light source powers after processing the background noise. Experiments demonstrate that the method has improved the stability of the system and it also applies to the stability measurement in strain and pressure experiments.
