“…The authors of [ 85 ] have presented the method for an impact source localization not only along the cable, but also away from it. To determine the location of the perturbation (impact source) and its distance from sensing fibers, arrays of weak-FBGs (wFBGs) inscribed in parallel sensor fibers were implemented ( Figure 8 ).…”

“…The transportation of resources such as oil and natural gas is closely related to the national economy and people's lives, but transmission pipelines may fail due to external invasion, corrosion, and other reasons, threatening the safety of personal, profits, and property. The DAS system based on discrete enhanced optical fibers was applied for pipeline safety monitoring due to its high SNR and high stability [77,78].…”

“…The fiber-optic vibration sensor is attracting attention because of its lightweight, simple structure, antielectromagnetic interference, and intrinsic explosion-proof characteristics, which can effectively solve the problem of long-term work in harsh working conditions. At present, the reported fiber-optic vibration sensor structures mainly include Fabry-Perot interferometer (FPI) [13][14][15], fiber Bragg grating (FBG) [16][17][18], Mach-Zehnder Interferometer (MZI) [19][20][21], etc. Yu et al proposed a fiber-optic vibration sensor with FPI using Kagome structured hollow-core photonic crystal fiber, with a single-frequency signal measurement range of 1 Hz to 20 kHz, but the sensor output signal would be slightly distorted [22].…”

With their long transportation distance and high productivity, belt conveyors are characterized as the main equipment for bulk material transportation in coal mines and other key industries. However, its speed detection method has always been an engineering challenge under harsh working conditions. In this work, the elastic-optical effect of the polarization-maintaining fiber is used to design a fiber ring laser vibration sensing system based on a fiber-optic Sagnac interferometer vibration sensor and its packaging structure. The vibration detection is achieved by detecting the change in optical power at the working wavelength, and the belt conveyor speed measurement is completed by detecting the vibration frequency. With such a method, the belt conveyor speed measurement obtained a relative error of less than 1.88%. The proposed method bears the characteristics of anti-electromagnetic interference, intrinsic explosion-proof, and adapts to the harsh smoke and dust working environment, which has a wide range of application prospects in the fields of engineering, machinery, security, etc.
