A FIBRE OPTIC EXTRINSIC FABRY-PEROT INTERFEROMETER WITH TEMPERATURE COMPENSATION FOR FAULT MEASUREMENT

  • 摘要: 针对光纤EFPI传感器通常尺寸很小,而断层尺寸相对较大,导致光纤EFPI传感器在待测断层处安装不便的情况,提出了一种可用于断层测量的光纤外腔型法布里-珀罗位移传感器。两根陶瓷插芯从陶瓷套管的两端插入构成EFPI结构,通过使用金属内管和金属外管,增大了光纤EFPI位移传感器的尺寸;并且金属外管的两端采用O型圈密封,因此该EFPI位移传感器能够防水防尘。为了消除温度对EFPI位移传感器的影响,两根金属内管采用了不同热膨胀系数的材料在结构上进行温度补偿。在温度连续变化的环境下,对腔长为718.39 m的EFPI位移传感器进行了测量。测量结果显示,经过温度补偿设计后,位移传感器的温度系数由0.14 μm/℃下降到了-0.04 μm/℃,并呈现过补偿。
