| 摘 要： | 基于高斯函数与光谱信号的相似性,采用高斯函数来对离子敏光纤传感器阵列—光纤舌信号进行仿真。利用Matlab对光纤舌可能检测到的发生光谱叠加的光谱信号进行分离和相对误差分析。从仿真结果可知,采用相应的算法可以减小由于重金属离子敏感膜的离子间干扰引起的光谱重叠误差。在此基础上,进行了带有光噪声光纤舌光谱叠加信号的信号处理仿真,为实际光纤舌的制作和光谱信号处理提供了理论依据。

| Abstract: | Based on approximation between Gauss function and spectral signal, Gauss function is utilized to simulate signal of optical fiber sensor array sensitive to ion, optical fiber tongue. Division of superposition spectral signal detected by optical fiber tongue and analysis of relative error are carried out by Matlab software. From result of simulation, it is known that superposition error of spectral caused by interference between ions in films sensitive to heavy metal ions can be reduced with corresponding algorithm. On this basis, superposition signals processing and simulation with optical noises in optical fiber tongue are carried out, provides theoretical foundation for preparation of practical optical fiber tongue and spectral signal processing . |
