Abstract
In this article, an integrated optical fiber sensor is designed and experimentally demonstrated for simultaneous measurement of magnetic field, displacement, and temperature. Only a long-period fiber grating (LPFG) is inscribed onto a single-mode fiber (SMF), and the LPFG is affixed through a hole in a magneto-strictive material, which is employed to detect magnetic field. Then, a balloon-shaped structure, achieved by utilizing the hole, has ability to monitor displacement and temperature. The highest sensitivities of the sensor are obtained as 1.039 nm/mT, − 467 pm/μm and 42.92 pm/℃. By solving the matrix equation, simultaneous measurement of above-mentioned parameters is achieved. Compared with previously reported sensors, the unique structures have advantages of compact volume, high sensitivity and robust, which satisfied demands of multi-parameter detecting under condition of high-intensity magnetic field and strong electromagnetic interference.
