摘要
提出了一种基于低通滤波和曲线拟合的光谱重建法,用于光纤光栅传感器波长检测,能兼顾高精度与实时性要求．仿真和实验结果表明,波长检测精度比直接寻峰提高了一个数量级．
This paper investigated a spectrum reconstructing method based on low-pass filtering and curve fitting, which can meet the requirement of real-time measurement as well as high accuracy for wavelength detection in a fiber Bragg grating sensing system. And the simulation and experimental results confirmed that the wavelength detection accuracy was improved by an order of magnitude compared with that obtained from direct peak search.
