| 摘 要： | 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。

| Abstract: | This paper for the first time proposed a method by using the weighted sum of each sensor’s feedback signal to control the input polarization state of the multiplexing system. The theoretical analysis shows that the control result of this method approximates to the ideal value of the array’s lowest visibility. Each sensor’s visibility can further reach 1 by signal processing, which eliminates the polarization induced fading in each sensor of the array. |
