摘　　要：为了实现长周期光纤光栅(LPFG)边缘滤波动态解调,利用LPFG的线性滤波特性,并结合压电陶瓷(PZT)的压电效应,提出一种基于双芯LPFG边缘滤波光纤布喇格光栅(FBG)动态解调系统。对该系统进行理论分析、可行性分析和仿真分析,并与静态滤波系统进行比较。结果表明:该系统具有较高的稳定性、精度和线性度。In order to realize the dynamic demodulation of LPFG edge filtering, a dynamic demodulation sys- tem of FBG based on twin-core long-period fiber Bragg grating （LPFG） is proposed by using the linear filter- ing characteristic of LPFG and the piezoelectric effect of piezoelectric ceramic（PZT）. The theoretical analysis, feasibility analysis, simulation analysis of the system are carried out, and compared with static filtering sys- tem. The results show that the system has hi~_h stability, precision and linearitv
