Abstract

We have proposed and experimentally demonstrated a vector magnetic field sensor based on a magneto-sensitive functionalized three-core fiber (TCF) structure. The fiber-optic magnetic field sensor adopts a sandwich-like magnetofluid encapsulated single-mode fiber (SMF)-TCF-SMF structure. Owing to the noncircular symmetric structure, thereby enabling the fiber sensing structure exhibits response to environmental magnetic field strength and direction. The experimental results shows that the maximum strength sensitivity and direction sensitivity are −1.23 nm/mT and 0.73 nm/°, respectively, within the range of 35–44 mT when the TCF length is 10 mm. The proposed magnetic field sensor offers several advantages, including simple structure, ease of fabrication, and high sensitivity.

基于磁敏功能化三芯光纤结构的矢量磁场传感器

我们提出并实验演示了一种基于磁敏功能化三芯光纤（TCF）结构的矢量磁场传感器。光纤磁场传感器采用三明治状磁流体封装单模光纤(SMF)-TCF-SMF结构。由于非圆对称结构，从而使光纤传感结构对环境磁场的强度和方向表现出响应。实验结果表明，当TCF长度为10 mm时，在35 ~ 44 mT范围内，强度灵敏度和方向灵敏度分别为- 1.23 nm/mT和0.73 nm/°。所提出的磁场传感器具有结构简单、制作方便、灵敏度高等优点。
