【摘要】 和串联复用相比,光纤法布里-珀罗传感器的并联复用结构简单、稳定性强、易于实现,因而具有较高的实用价值。本文基于光纤法布里-珀罗传感器的基本原理,分析了两只光纤法布里-珀罗传感器并联复用条件下系统的组合输出光强信号特征;讨论了利用傅立叶变换的方法对此组合光强信号进行解调的原理及实现方法;最后对两只传感器的并联复用进行了计算机仿真实验,仿真结果表明光纤法布里-珀罗传感器并联复用方案是可行的。
【Abstract】 Comparison with it’s series multiplexing, the parallel multiplexing of optical fiberFabry-Perot sensor is of high practical value, due to the characters of the simple structure, highstability and ease to be realized. According to the principle theory of the optical fiber Fabry-Perotsensor, The characteristics of combinatorial output of parallelly multiplexed sensors were discussedin details; The demodulating theory and realization were also discussed by using FourierTransformation; and the multiplexing capacity was discussed later. Finally, the simulatedexperiment was completed. The results showed that the parallel multiplexing of the optical fiberFabry-Perot sensors is available.
