“…6(a), the phase curve is somewhat unsmooth, which may be due to the nonlinear response of the sensor, the power frequency vibration of the vibration platform and the fluctuation of the demodulation system. In the reported literatures [16], [17], [27], the lowest frequency that can be measured by sensors based on fiber-optic EFPI is generally not less than 10 Hz. To some extent, the performance of fiber-optic accelerometer in low frequency band is a breakthrough in this area of research.…”

“…In recent years, with the development of grating etching, femtosecond laser processing, microelectro-mechanical system and other technologies, a variety of fiber accelerometers with high precision and multi-parameter measurement function have been reported. For instance, W. Zhang et al [16] reported a kind of sensor which realized double parameter measurement of acceleration and magnetic intensity based on F-P interference and a kind of fiber Bragg grating based accelerometer. Q. Yu et al [17] reported F-P accelerometer based on fast white light interference.…”

A fiber-optic accelerometer based on extrinsic Fabry-Perot interferometer (EFPI) is reported. The sensor adopts flywheel diaphragm structure as a sensitive element, where the mass block is bonded in the center, while the beam of the flywheel acts as a spring. The sensitive element forms single degree of freedom spring-mass-damper system. The parameters of the accelerometer are designed based on finite element simulation (FEM), and the transfer function of the sensor is established by numerical simulation. The experiments indicate that the sensor has a wide detection frequency band with the detectable ability for micro-vibration low as 0.01 Hz, and the sensitivity is 7.02 rad/g @20 Hz, and reach an average sensitivity of 6.39 rad/g in 5-20 Hz. The research shows that the accelerometer has a good development prospect in the field of low frequency micro-vibration detection.

The magnetic field is a vital physical quantity in nature that is closely related to human production life. Magnetic field sensors (namely magnetometers) have significant application value in scientific research, engineering applications, industrial productions, and so forth. Accompanied by the continuous development of magnetic materials and fiber-sensing technology, fiber sensors based on the Magneto-Refractive Effect (MRE) not only take advantage in compact structure, superior performance, and strong environmental adaptability but also further meet the requirement of the quasi-distributed/distributed magnetic field sensing; they manifest potential and great application value in space detection, marine environmental monitoring, etc. Consequently, the present and prevalent Magneto-Refractive Magnetic Field Fiber Sensors (MR-MFSs) are briefly summarized by this paper, proceeding from the perspective of physicochemical properties; design methods, basic performance and properties are introduced systematically as well. Furthermore, this paper also summarizes key fabrication techniques and future development trends of MR-MFSs, expecting to provide ideas and technical references for staff engaging in relevant research.
