干涉型光纤传感器输入偏振态反馈控制的理论分析

Theoretical Analysis of Interferometric Fiber Optic Senors′s Input Polarization Control

对光纤干涉仪输入偏振态的反馈控制机理进行了新的理论分析和研究，得出了反馈控制系统的反馈信号，分析了光纤偏振控制器电压初始值要求和该反馈控制系统可能存在的稳定点，并建立了反馈控制模型。

A new theoretical analysis is given for the feedback control principle of the interferometric fiber optic sensor′s input polarization control. The suitable feedback signal is obtained, the requirement of the orginal control voltage and the possible steady point of the control system is analysed, and the feedback control model is set up. The theoretical conclusions consist with the experimental phenomena in the reference .
