Special Issue Information

Dear Colleagues,

Optical fibre sensors, ever-advancing, are continuing to be widely adopted, making inroads into virtually every industry as a result of their outstanding properties, such as high inherent sensitivity, immunity to electromagnetic interference, high signal-to-noise ratio, inertness, remote sensing, distributed sensing, multi-parameter sensing, light weight, multiplexing capabilities, etc.

This Special Issue will show-case the varying capabilities offered by optical fibre sensors, especially in performing measurements in challenging applications. For example, optical fibre sensors are increasingly being deployed into environments that have been difficult or impossible to instrument using any other previous sensor technology. Challenging applications of interest include precision measurements (e.g., metrology, nano technology), structural health monitoring (e.g., aerospace, civil and military structures, advanced composites, automotive), robotics (e.g., manufacturing, surgical instruments, process industries), harsh environments (e.g., turbomachinery, nuclear plants, submarine, offshore oil and gas, combustion chambers, explosives), medical field (e.g., implants, wearables, surgical instruments), renewable energy (e.g., wind turbines, tidal turbines), material characterisation (e.g., advanced composites, nano materials), manufacturing (e.g., process monitoring, additive manufacturing, 3D printing), environmental measurements (e.g., gas sensing, exhaust emissions, air-borne detection, aerodynamics, flow measurement), and other applications.

Well-established, novel, and disruptive sensors are welcome, as are tools and methodologies that unlock access to untouched application areas. The radical development and application of new sensing approaches are also areas of interest.

The determination of the arc rating of arc-resistant materials for the manufacture of personal protective clothing is conducted by measuring the incident and transmitted energies through calorimetry using thermocouples coupled to copper discs during the electric arc events. In this study, custom calorimeters were constructed by incorporating both a thermocouple wire and an embedded optical-fiber temperature sensor, and the arc ratings of different fabrics were determined in terms of their arc-thermal-performance value (ATPV). The results revealed differences between the measurements obtained with the two sensor types. Notably, the absence of electromagnetic interferences generated by the arc current and the enhanced time response achieved with the optical-fiber temperature sensor signal led to an ATPV arc rating approximately 27% lower than that measured with the thermocouple. These findings underscore the importance of investigating the current methodology used for determining arc ratings to ensure accurate measurement of incident and transmitted energy. Full article
