Abstract
提出了两种简单的磁致伸缩调制型光纤 Bragg 光栅的温度补偿方法。利用磁场和磁致伸缩材料对光纤光栅的 Bragg 波长进行调制, 将一对光纤光栅按特定的结构固定, 使得磁致伸缩效应对两只光纤光栅的 Bragg 波长的调制效果相互迭加而温度的影响相互抵消。补偿后的磁场调制型光纤光栅温度在 22～ 80℃ 的范围内, 波长变化仅为0.11nm, 其温度灵敏度是温度补偿前的 1/10。
Two simple techniques for the compensation of the temperature effects in fiber Bragg gratings tuned by magnetostrictive transducers were demonstrated. The Bragg wavelengths were tuned by the magnetic field through the magnetostrictive transducer and two fiber Bragg gratings are arranged in such a way that the magnetostrictive effects on these gratings are added together, while the temperature effects are cancelled. It can reduce the temperature sensitivity of the sensor by more than 10 times, and the additional wavelength shift due to the temperature is only 0.11 nm within the range of 22°C-80°C.
