To address the issue of temperature cross-sensitivity in refractive index （RI） measurement， a fiber-optic Surface Plasmon Resonance （SPR） sensor based on dual D-shaped no-core fiber （NCF） is proposed and designed. The sensor mainly consists of D-shaped NCF， Ag/Fe2O3composite film， and polydimethylsiloxane （PDMS）， where the silver and Fe2O3are successively coated on both D-shaped surfaces of NCF to generate SPR and enhance the oxidation resistance. The layer of PDMS coated on one D-shaped surface acts as a tunable ambient medium sensing the temperature variation and affecting the transmission spectrum of the sensor. Since the surface plasmon waves are excited in the two D-shaped surfaces with different films， the two RI and temperature-dependent spectral resonance peaks with different wavelengths will be produced. Research results demonstrate that the two peaks’ wavelengths have different responses to the variations of ambient RI and temperature. In the refractive index range of 1.36-1.376 and temperature range of 10-100 °C， the RI and temperature sensitivities reach to 5000 nm/RIU and -0.546 nm/°C， respectively. With the sensitivity coefficient matrix， simultaneous measurement of refractive index and temperature can be realized， and the corresponding accuracy is superior to 0.4×10-5RIU and 0.037°C.

针对可调谐光纤法布里-珀罗滤波器在光纤光栅解调中受到迟滞和温漂特性影响导致解调误差增大的问题,提出一种基于麻雀搜索算法优化支持向量回归的光纤光栅波长解调方法。采用滑动窗口与支持向量回归结合的方法构建可调谐光纤法布里-珀罗滤波器的波长补偿模型。实验结果表明,当锯齿波调谐频率为0.5 Hz时,该模型补偿后的漂移波长平均绝对误差和均方误差分别降低至18.47 pm和1.21 pm。稳定性测试中,该方法解调波长值与sm125解调值之间的平均绝对误差为7.28 pm;40~90℃降温实验中,该解调方法的平均绝对误差为7.44 pm。此方法验证了光纤光栅解调系统在不借助硬件参考的情况下,可以有效降低光栅波长解调误差。
