摘要
在仔细分析了构成光纤光栅(FBG)传感网络光路各部分的光信号特征的基础上,建立了FBG传感网络的数学模型,同时分析了可能导致传感信号测量误差的因素,提出了一种波长偏移矫正的方案,这种波长偏移矫正方案应用于采用波分复用技术的传感系统和光源中心波长与FBG中心波长不匹配的传感网络,减小了波分复用网络的测量误差,有效地提高了测量精度。
Through the obtained phenomena in the experiment, the effects of the throughout neglected source and transmission system on the measurement signals and on the limitation of FBG sensors in WDM network were discussed. A method to overcome these effcts is proposed to reduce the measurement error in WDM network and to improve the measurement accuracy.
