摘　　要：基于啁啾光纤光栅和长周期光栅,文章提出一种应用于聚合物微环传感器和微环传感器阵列的信号解调方法。通过调整长周期光栅的峰值波长来匹配感测范围,从而实现线性边沿滤波。该系统由全光纤器件组成,这种解调可以达到31 pm的高分辨率。双通道系统中,每个通道的波长带宽为2.4 nm。On the basis of chirped fiber gratings and long-period gratings,a novel signal demodulation method for polymer micro-ring sensors and micro-ring sensor arrays is presented.Linear edge filtering is realized by adjusting the peak wavelength of the long-period gratings to match the range of sensing.In this method,demodulation is achieved with high resolution of 31pm and in dual-channel systems and the wavelength bandwidth of each channel is 2.4 nm.This system is composed of all-fiber devices.
