摘　　要：为解决普通光纤布喇格光栅(FBG)双边缘滤波解调系统只能解调固定且窄范围波长的问题,提出一种可调谐环形双边缘滤波解调系统。将4个特征光谱连续且两两相交的滤波器镶嵌在一环形器上,测量时,根据需要调节档位,选择合适的带宽范围。In order to solace the problem of the ordinary double edge filter FBG demodulation system only de- modulates wavelength which fixed and narrow range, the paper proposes a tunable circular double edge filter demodulation system. Four filters of continuous and pairwise intersecting characteristic spectrum are mounted on a ring-shaped device, thus according to needs to choose a different bandwidth when measuring.
