摘要 通过分析光纤干涉仪输出信号成分和理论推导,提出了干涉型光纤传感器相位生成载波(PGC)调制解调技术的改进方案,通过实验仿真得出,新方案不需要AGC模块就可以消除干涉仪输出光功率漂移对解调结果的影响,而且系统的最低采样频率减低了约1/3。 An improved scheme of phase generated carrier（PGC）demodulation technology based on interference pattern optical fiber sensor is put forward by analyzing output signal component of the optical fiber interferometer and the theoretical deduction.Through simulation,influence of the interferometer output light power drift on the effect of demodulation can be eliminated without AGC module.The minimum sampling frequency of the system has been reduced by a third.
