干涉型光纤传感器解调技术的研究

摘要

The paper introduces the operating principle of phase modulation,analyzes the prime elements which influence the stability of demodulation signal.On this basis,an improved method is put forward and a set of perfect fiber sensing system is established. Through a lot of experiments and analysis,error is reduced and examination sensitivity becomes higher.%首先介绍了相位载波调制的工作原理，然后从理论上分析了影响解调信号稳定性的主要因素，在此基础上提出了改进的方法，建立了一套较为完善的光纤传感系统。经过大量的实验论证，对比分析，减小了误差，获得了较高的检测灵敏度。
