摘要
建立了基于3×3耦合器的光纤Mach-Zehnder(MZ)干涉型传感系统。在对3×3耦合器信号解调方案进行了推导和分析后,对干涉信号中偏振衰落现象进行了理论分析和实验研究,并指出了它对3×3耦合器信号解调方案的影响。针对偏振衰落现象的特点,提出了消除这一问题的方案,实现了干涉仪信号的无偏振衰落输出。
A Mach-Zehnder（MZ） inter[erometer sensor system based on a 3 × 3 coupler demodulation method was presented. The 3 × 3 coupler demodulation method was deduced. The polarization fading was studied in theory and in experiment. And its influence on the 3 × 3 coupler demodulation method is analyzed. Through theoretical analysis, the method to restrain polarization fading is put forward.
