| 摘 要： | 研究了基于可调谐滤波器(TOF)的带中心波长自动跟踪光纤光栅动态波长解调技术。实验表明,解调仪特别适合在传感FBG(fiber Bragg grating)存在大幅度静态波长变化时对微幅度动态波长变化进行检测,动态波长检测分辨率为0.007pm/Hz。上电时,TOF对中心波长为1292.50~1308.50nm范围内的光纤光栅具有自动跟踪的能力,克服了TOF不稳定对系统的影响。

| Abstract: | A fiber Bragg Grating dynamic interrogation technique based on the tunable optical filter(TOF) was investigated.The experiments demonstrate this interrogation technique is very 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/.The TOF can track the FBG center wavelength between 1298.50nm and 1308.50nm when the system is power-on,moreover it can overcome the negative influence due to the instability of the TOF. |
