提出了一种新型的光纤布拉格光栅辅助光纤环路衰荡(FLRD)传感器阵列及其基于波长-时间复用的解调技术。给出了系统的询问频率公式，分析了系统参数之间的相互关系。为了验证该系统的性能，对一个五元阵进行了实验验证，该系统能够在125.5赫兹的询问频率下对每个单元进行实时监测。
A novel fiber Bragg grating aided fiber loop ringdown (FLRD) sensor array and the wavelength-time multiplexing based interrogation technique for the FLRD sensors array are proposed. The interrogation frequency of the system is formulated and the interrelationships among the parameters of the system are analyzed. To validate the performance of the proposed system, a five elements array is experimentally demonstrated, and the system shows the capability of real time monitoring every FLRD element with interrogation frequency of 125.5 Hz.
