摘要
对干涉型光纤传感器中光波偏振态的随机变化导致待检测信号衰落的原理进行了理论分析，系统地总结了目前国内外关于双光束干涉型光纤传感器抗偏振消衰落措施的最新研究成果。
This paper gives a theoretical analysis of the principle of signal fading in interferometric fiber optic sensors,which is induced by random fluctuations in the state of polarization (SOP) of the interfering beams propagating in the interferometer,and summarizes comprehensively the brandnew polarizationinducedfading elimination techniques for twobeam interferometric fiberoptic sensors at home and abroad.
