“…1 Both the integration and the performance enhancement methods are included in the table. 2 Since the criterion of the provided results is not consistent among the reviewed works, here, the unit "MHz" represents the BFS measurement accuracy, the unit " • C" represents the temperature measurement accuracy or resolution, and the units with "ε" or "nε/ √ Hz" represent the strain measurement accuracy or sensitivity. As mentioned in Section 3, separating different backscattering lights is a key process to realize the hybrid DOFS system.…”

“…In recent decades, optical fiber sensors (OFSs) have been developed rapidly with the growth of fiber optic communication technology. OFS offers many strengths, such as immunity to electromagnetic interference, high sensitivity, robustness, and flexibility [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. The application of OFS begins with single-point sensing, which is hard to implement in a long-distance monitoring scenario [ 11 , 12 , 13 ].…”

Distributed optical fiber sensors (DOFSs) are a promising technology for their unique advantage of long-distance distributed measurements in industrial applications. In recent years, modern industrial monitoring has called for comprehensive multi-parameter measurements to accurately identify fault events. The hybrid DOFS technology, which combines the Rayleigh, Brillouin, and Raman scattering mechanisms and integrates multiple DOFS systems in a single configuration, has attracted growing attention and has been developed rapidly. Compared to a single DOFS system, the multi-parameter measurements based on hybrid DOFS offer multidimensional valuable information to prevent misjudgments and false alarms. The highly integrated sensing structure enables more efficient and cost-effective monitoring in engineering. This review highlights the latest progress of the hybrid DOFS technology for multi-parameter measurements. The basic principles of the light-scattering-based DOFSs are initially introduced, and then the methods and sensing performances of various techniques are successively described. The challenges and prospects of the hybrid DOFS technology are discussed in the end, aiming to pave the way for a vaster range of applications.

“…The most frequently used field sensors are the ones used for the measurement of small field variations or field gradient or magnetic anomaly detection (MAD) [131]. Fibre optics are widely used as magnetometers [132][133][134][135][136]. The most important techniques and effects used to develop such field sensors based on magnetic materials are the MR effect, the MI effect and inductive techniques like fluxgates.…”

A review of the engineering theory and the sensing element applications of the magnetostrictive delay line (MDL) technique is presented. The state of the art of magnetic materials and effects used in sensor design is overviewed and the operation of MDLs and their basic engineering properties are discussed. The resulting position, stress and field sensors based on this technique as well as their most significant applications are demonstrated. Finally, the industrialization process and the integration of the sensors with electronic circuitry as well as their evaluation with respect to the state of the art are discussed.

“…Over the past few years, researchers have been paying attention to a new all-fiber Fabry-Perot interferometers technique fabrication [1], driven by the interest to improve its sensibility, resolution, and stability. As a result, several fabrication techniques have been proposed, and their sensing applications, such as temperature [2], [3], refractive index [2], [4], [5], curvature [6], magnetic field [7], strain [3], [8], load [9], pressure [10], etc, have been demonstrated. Some prior works propose using a high power pulse laser to create a micro machined FP cavity at the tip of conventional single mode fiber (SMF28) to detect refractive index changes, and these experiments show is possible to obtain a high resolution using this FP structure; however, the fabrication cost increase by the kind of laser used [4].…”

An all-fiber Fabry-Perot (FP) interferometer is proposed and validated by the arc splicing technique. By using conventional fiber and special hollow-core photonic crystal fiber, several FP cavities were formed at the conventional fiber tip using arc discharges. As a result of the interaction between these cavities, modified FP principle operation was obtained; and temperature, refractive index, and load analyses validated this operation modification. In addition, this all-fiber interferometer presents good resolution and sensitivity in each parameter examined. The structure offers compactness, robustness, high repeatability, and stability measurement.
