Electromagnetic field sensors are widely used in various areas. In recent years, great progress has been made in the optical sensing technique for electromagnetic field measurement, and varieties of corresponding sensors have been proposed. Types of magnetic field optical sensors were presented, including probes-based Faraday effect, magnetostrictive materials, and magnetic fluid. The sensing system-based Faraday effect is complex, and the sensors are mostly used in intensive magnetic field measurement. Magnetic field optical sensors based on magnetic fluid have high sensitivity compared to that based on magnetostrictive materials. Three types of electric field optical sensors are presented, including the sensor probes based on electric-optic crystal, piezoelectric materials, and electrostatic attraction. The majority of sensors are developed using the sensing scheme of combining the LiNbO3 crystal and optical fiber interferometer due to the good electro-optic properties of the crystal. The piezoelectric materials-based electric field sensors have simple structure and easy fabrication, but it is not suitable for weak electric field measurement. The sensing principle based on electrostatic attraction is less commonly-used sensing methods. This review aims at presenting the advances in optical sensing technology for electromagnetic field measurement, analyzing the principles of different types of sensors and discussing each advantage and disadvantage, as well as the future outlook on the performance improvement of sensors.

“…Moreover, its sensitivity is dropped after multiple uses due to the probable accumulation of magnetic nanoparticles on the deposited layer that may cause a considerable loss of induced strain by an external magnetic field. Although integrated FBG-FPI fiber sensors for measuring multiple parameters have been reported, to the best of our knowledge, this combined configuration has not been applied to the magnetic field and MF refractive index detection [29][30][31][32][33][34][35][36][37][38]. Therefore, in this study, a dual FPI-FBG fiber sensor device with specific modification is established to overcome magnetic field and refractive index parallel multi sensing challenges, which applies to reservoir engineering.…”

In this paper, a sensor combining Fabry–Perot interferometer (FPI) with fiber Bragg grating (FBG) is designed, fabricated, and experimentally demonstrated as an excellent alternative to traditional sensors to detect the magnetic field and refractive index (RI), simultaneously. The sensor comprises a magnetostrictive Ni-Fe alloy coated on partially-unclad FBG, connecting the two reﬂecting surfaces of the micro-FPI cavity. The magnetostrictive analysis shows that magnetostriction reaches the maximum value at 59.3% Ni concentration. The sensor performance test was conducted on the RI of magnetic fluid and external magnetic field changes. The probe sensitivity was found to be as high as 625.38 nm/RIU and 7.71 nm/mT, respectively. A matrix for simultaneous measurement of the magnetic field and RI was constructed using these sensitivity values. The stability of the sensor system over more than 300 hours is at a satisfactory level. Considering the accurate FBG modulation and particular design of the experiment proposed by this method, the resolution of 1.69×10-4 RIU and 0.016 mT for magnetic fluid and magnetic field could be achieved, respectively, which can meet the sensing demand for a wide range of applications.

Based on the low-coherence interferometric principles, a cost-effective all-fiber Mach-Zehnder multiplexing system is proposed and demonstrated. The system consists of two interferometers: sensing interferometer and demodulation interferometer. By scanning an optical tunable delay line back and forth constantly with a stable speed, sensing fibers with different optical paths can be temporal interrogated. The system is experimentally proved to have a high performance with a good stability and low system noises. The multiplexing capacity of the system is also investigated. An experiment of measuring the surrounding temperature is carried out. A sensitivity of 12 m/ is achieved within the range of 20 ℃ to 80 ℃ . This low cost fiber multiplexing system has ℃ a potential application in the remote monitoring of temperature and strain in building structures, such as bridges and towers.
