During the design of a practical interferometricfiber-opticsensor, one of the key problems is to compensate phase random shifting and eliminate frequency doubling caused by strong signal.
在干涉型光纤传感器的实用化设计过程中，相位随机漂移补偿及强信号下出现的倍频的消除是关键问题之一。

Interferometricfiberopticsensor is an important category of fiber-optic sensor because of its high sensitivity.
干涉型光纤传感器因其灵敏度很高而成为光纤传感器研究的一个重要组成部分。
