“…As a type of interferometric DFOS, POF sensors offer better structural flexibility and resistance to external disturbances and deformations in harsh construction environments. This makes POF sensors suitable for embedded sensors in reinforced structures [146]. Preliminary results show that POF sensors can be used for SHM [118].…”

Structural health monitoring is currently a crucial measure for the analysis of structural safety. As a structural asset management approach, it can provide a cost-effective measure and has been used successfully in a variety of structures. In recent years, the development of fiber optic sensing technology and vision sensing technology has led to further advances in structural health monitoring. This paper focuses on the basic principles, recent advances, and current status of applications of these two sensing technologies. It provides the reader with a broad review of the literature. It introduces the advantages, limitations, and future directions of these two sensing technologies. In addition, the main contribution of this paper is that the integration of fiber optic sensing technology and vision sensing technology is discussed. This paper demonstrates the feasibility and application potential of this integration by citing numerous examples. The conclusions show that this new integrated sensing technology can effectively utilize the advantages of both fields.

“…Preliminary results show that POF sensors can be used for SHM [118]. Recently, Dong Luo et al [146] proposed a corrosion-monitoring device based on a tapered polymer optical fiber sensor (TPFS) for steel bars. This is a novel non-destructive approach to monitoring the corrosion condition of steel reinforcements.…”

“…Another interesting corrosion discovery solution is presented in [46], where a measuring cell employing an unclad sapphire fber waveguide operating in the visible spectral range is capable of detecting iron ions released due to the formation of rust. Authors have reported a corrosion sensor based on a tapered polymer optical fber [47], where the accumulated corrosion between the steel and the sensor produces strain, which translates into the change of optical power transmission of the sensor. Fabry-Perot-based corrosion sensors [48] were also reported in the past for corrosion sensing.…”

This paper presents a fiber optic sensor for the detection of corrosion processes that occur on metal surfaces. In the proposed sensor design, a sensing fiber with an inscribed high-order Bragg grating is attached to the observed metal surface. A broadening of high-order Bragg grating spectral characteristics is observed and used to detect small and highly localized longitudinal strain variations that occur along the fiber as a result of corrosive rust flakes’ formations beneath the sensing fiber. The proposed approach provides a straightforward fabrication method, the possibility for unobtrusive mounting, including mounting of the sensor beneath the corrosion-protective layers, and consistent corrosion detection yields.
