This article experimentally validates a high-sensitivity vector magnetic field (MF) sensor based on two parallel Fabry-Perot interferometers (FPIs). Firstly, standard single-mode fibers are interposed into capillary tube to constitute cantilever beam structure FPI1. FPI1 achieved high axial strain sensitivity of 15.0 pm/µε. Then, was bonded with the magnetostrictive material Terfenol-D, and its MF intensity direction reached 91.43 pm/mT -12.75 pm/°, respectively. Finally, reference interferometer FPI2 matched harmonic Vernier effect S1. The average S1 reaches -4.308 nm/mT, 892.3 pm/°. It amplifies by 47 times 33.0 times, Therefore, proposed can measure sensitivity. Additionally, only involves fiber optic cutting, splicing, cold bonding during manufacturing process, without damaging optic. it is easy manufacture, highly reproducible, cost-effective, structurally robust, operate. one preferred choices for sensors in practical applications.
