马赫-曾德尔光纤干涉仪的偏振态反馈控制的DSP实现
SP’s realization by feedback control of the Mech-Zehnder fiber interferometric’s input polarization
本文根据马赫-曾德尔光纤干涉仪输入偏振态的反馈控制机理，设计了一个系统来实现对输入光偏振态的反馈控制。系统的核心是TI公司的数字信号处理器TMS320F2812，通过每秒2000次的采样和每秒钟一次的控制频率，使光纤干涉仪的两路干涉臂的偏振态保持平行。本文详细介绍了系统的结构搭建和反馈控制的算法，并根据实验结果分析证实该反馈控制理论可行。
In this paper, a system is designed for the feedback control, according to feedback control principle of the Mech-Zehnder fiber interferometric’s input polarization control. The system’s core is TI’s digital signal processor TMS320F2812, which controls interferometric’s polarization by 2000 times sampling and one time controlling per-second. The system’s structure and feedback control algorithm is discussed in detail, and the experiment results prove that this feedback control theory workable.
