摘要
毛细管式封装光纤布拉格光栅(Fiber Bragg Grating, FBG)工艺会对其温度传感特性产生重要影响, 为了研究其影响机制, 分别采用改性丙烯酸酯和环氧树脂将受预应力的FBG封装在毛细锌管内, 进而利用方便且准确的水浴法进行温度传感试验。结果表明, 与没有进行任何封装工艺的裸光栅相比, 采用封装方法后, FBG的温度灵敏度大幅上升, 分别提高到21.87、35.13 pm/℃, 为裸光栅的2.3、3.6倍, 响应速度无明显变化, 中心波长也具有良好的稳定性。
Abstract
The capillary encapsulating technology on Fiber Bragg Grating(FBG)have a significant impact on its temperature sensing characteristics. In order to study its influencing mechanism, two FBGs were capillary encapsulated in zinc capillary with modified acrylate and epoxy resin respectively. The temperature sensing test was performed by using a convenient and accurate water bath method. The results show that compared with the bare grating without any packaging process, the temperature sensitivities of the encapsulated FBGs are 21.87 pm/℃、35.13 pm/℃, which are 2.3 times and 3.6 times of the bare grating. No significant change in response speed, the center wavelength also has a good stability.
