Special Issue Information

Dear Colleagues,

Photonics is closely related to the technology of generating and using light and other forms of radiant energy whose quantum unit is the photon. Photonics involves a wide range of applications of lasers, optics, solid-state lighting, fiber optics, electro-optical devices, and inter alia photonic sensors.

The aim of this Special Issue is the presentation of recent advances in photonic sensors, based on different configurations and materials that can be used in numerous and diverse fields of technology as alternate energy, manufacturing, health care, telecommunication, environmental monitoring, homeland security, and aerospace.

Applications of the photonic sensors may cover many areas, ranging from new concepts still experienced in laboratories to sensing systems to be made available on the market, even in highly differentiated sectors, such as biomedicine and biotechnology, micro- and nanotechnology, construction and engineering, alternate energy and green solutions, chemical technology, transportation, gas sensing, defense, space, and so on.

We kindly invite you to submit a manuscript(s) for this Special Issue. Full papers, communications, and reviews will be more than welcome.

The technology of polymer microtips’ manufacturing on the ends of selected multi-mode fibers has been reported. The study’s key element was an extended description of technology parameters’ influence on the shape of these 3D microstructures. Basic technology parameters such as spectral characteristics of the light source, monomer mixture type, optical power, and exposure time were taken under consideration. Depending on those parameters, different shapes, sizes, and surface structures of microtips were obtained. The spectral characteristics of the light and optical power delivered to a monomer drop were identified as the most important parameters for the formation of the desired 3D shape of the microtip. Presented experimental results are the base for further studies directed to the application of these micro-elements in the fields of optical measurements and sensors’ technology. Full article

Abstract: With the growing use of high-performance composite materials in critical structures, it has become increasingly important for ‘smart’ fiber optic systems to monitor the structural health of these materials. The paper presents an overview of hybrid fiber optic sensor systems based on scattering techniques, fiber Bragg gratings and polarimetric methods in structural health monitoring. The main purpose of this manuscript is to analyze the possibilities of using hybrid sensors based on fiber optics to monitor composite structures, with particular emphasis on aircraft structures.

Abstract: Fiber Bragg gratings (FBGs) are considered as an excellent option to monitor micro cracks in engineering structures due to their ability to measure crack induced acoustic emissions (AE) and thereby have a great potential in structural health monitoring (SHM) to ensure the safe operation of structures. In this paper, various methods and technologies to monitor AE using FBG have been reviewed and discussed. This comprehensive review provides a detailed evaluation of the evolution of various FBG based AE systems from the outset to state of the art for acoustic and ultrasonic sensing for their use in different SHM applications. Recent trends and future challenges for AE sensing interrogation methods are also discussed.
