摘　　要：本文阐述了基于光纤光栅的边缘滤波动态解调技术的研究。初步实验表明:解调仪适合传感FBG存在大幅度静态波长变化时,对微幅度动态波长变化的检测,动态波长检测范围分辨率为0.007pm/!Hz。上电时,可调滤波器具有对中心波长为1295.5nm～1307.5nm范围光纤光栅自动跟踪能力。We report Edge Filter Dynamic Demodulation Method Based on Filter Bragg Grating. Initial experiments demonstrated this interrogation technique is suitable for the micro-amplitude dynamic wavelength detection existing in the large static wavelength change of the FBG, the dynamic wavelength detection resolution is 0.007pm/√Hz, The tunable optical filter can track the FBG center wavelength between 1295.5nm-1307.5nm when the system powered on.
