摘要
在基于当前FBG传感信号解调技术的基础上,提出了基于可调谐法布里-珀罗(F-P)滤波法和非平衡马赫-曾德尔(M-Z)滤波法的FBG解调方法,并进行了系统仿真模型的设计,对其仿真结果与单独的可调谐F-P滤波法和非平衡M-Z滤波法的仿真结果进行了比较。结果表明这种方法的性能得到了明显的提高,适用于FBG传感信号的静态和动态解调。
The paper analyzes the current situation of FBG sensing technology and Sensing signal demodula-tion technology,then researches a FBG sensing signal demodulation technology based on tunable F-P filtering method and unbalanced M-Z filtering method deeply,at last a combined method is proposed.In the end,the paper proposes a simulation model and compares it s results and that of tunable F-P filtering and unbalanced M-Z filtering results.The comparison shows that this new mixed demodulation technique is signific...
