摘要  介绍一种新的基于寄生干涉结构的干涉解调方案 ,它将包含应变信息的波长漂移信号变为相移信号 ,借助相位计显示的相移量确定待测应变量的大小 系统传感灵敏度的实验值为1.5 8Deg/ με ,在误差允许的范围内与理论值 1.6 1Deg/ με基本吻合 ,具有 0 . A fiber Bragg grating sensor demodulation system based on a parasitic interference scheme is reported.Measuring the phase-shift of the signal with a phase-meter can demodulate the strain. The sensing sensitivity of this scheme, which is with a resolution of 0.39 με, was demonstrated to be 1.58 Deg/με, experimentally. It basically matches the prospected value of 1.61 Deg/με.
