摘要
提出并实验演示了一种基于F-P可调滤波法对光纤光栅波长解调的新方案,利用参考光栅温度与其反射波长关系来检测传感光栅的波长移动量,该解调方法成本低。实验结果证明:采用此方法的解调系统波长测量精度达到5pm以上,有很高的稳定性,具有实际应用价值。
A new method wavelength interrogation system based on the optical fiber Fabry-Perot（F-P） tunable filter is proposed and experimentally demonstrated in this paper. The wavelength shifts of the sensing FBG is detected by use of the relationship between the reference FBG＇s temperature and its reflected wavelength, and the method is characteristic of low cost. It is proved that the demodulation method has characteristics of the measurement precisions of 5pm ,d good stability and the applicable value.,
