提出了在干涉型光纤传感器的复用系统中将各个传感器的输入偏振态反馈信号加权叠加用于复用系统输入偏振态控制的方案。经分析,该方案可达到的最小可见度与文献分析的复用系统输入偏振态控制的理想效果相接近。经过信号处理能使各个光纤传感器的可见度均达到其最大值1,从而消除了复用系统中各单元的偏振态衰落。
A scheme of weighting and superimposing the input polarization state feedback signals of each sensor in the multiplexed system of the interference optical fiber sensor is proposed for the input polarization state control of the multiplexed system. After analysis, the minimum achievable visibility of this scheme is close to the ideal effect of input polarization control of the multiplexed system in literature analysis. After signal processing, the visibility of each optical fiber sensor reaches its maximum value of 1, thereby eliminating the polarization fading of each unit in the multiplexing system.
