摘要:
 光纤布拉格光栅(FBG)传感器是通过观测光纤光栅反射谱中心波长漂移来判断待测量变化,准确寻找光纤光栅反射谱峰值信息成为研究重点。依据分布反馈式激光器(DFB)动态扫描输出波长与时间的规律,以标准法布理-珀罗透射谱为标准谱来直接获取光纤光栅中心波长信息,并采用高斯函数和洛仑兹函数两种拟合算法,对法布理-珀罗透射谱和FBG反射谱进行研究。采用曲线拟合度作为标准,运用编程语言编写寻峰算法并优化。实验结果表明,动态调谐的分布式反馈激光器光纤光栅波长解调系统高斯拟合算法优于洛伦兹拟合算法,拟合度可达到97%以上,系统测量分辨率达1pm、测量范围为1547~1552nm。
Abstract:
 The central wavelength of the reflecting spectra in Fiber Bragg grating (FBG) varies with the measuring parameters of external environment, which is the key point to confirm the reflecting peak information of the FBG. The central wavelength of the reflecting spectra in FBG was obtained by the standard FabryPerot transmission spectra based on the law between the dynamic scanning wavelength and scanning time of Distributed Feedback laser (DFB). The Gauss and Lorenz arithmetic function were used to investigate the FabryPerot transmission spectra and FBG reflecting spectra. The peakdetection algorithm was written and optimized by programming language based on the accuracy of curve fitting. The results show that the Gauss fitting algorithm is better than Lorenz fitting algorithm for the DFB dynamic scanning wavelength demodulation system. The fitting degree is more than 97%, the resolution of the measuring system is about 1 pm, and the measurement ranges from 1547nm to 1552nm.
