“…The locations of each sensor and the "h" region are as shown in Figure 12. In addition, Ho et al [120] presented an SHM system based on FBG sensors which provides accurate time-deformation relations and frequency spectrum results. Moreover, they used the system for the SHM of a linear robot (LR).…”

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.

“…However, there are limited detection methods for continuous online monitoring of large wind turbine blades, such as acoustic emission and strain monitoring 3 . In the practice of structural health monitoring, researchers have found that: fiber Bragg grating (FBG) sensors have unique advantages over electric strain gauges (SGs), such as immunity from electromagnetic interference, small size, lightweight, corrosion resistance, long-term durability, and stability, and now FBG is being used in aerospace, civil engineering, and other fields 4 , 5 . The development of structural health monitoring technology for wind turbines using FBG sensors has therefore attracted a lot of attention from researchers.…”

We designed a CFRP-FBG sensor with a "sandwich" structure consisting of carbon fiber reinforced polymer (CFRP) encapsulation layers and a fiber Bragg grating (FBG) for strain monitoring of wind turbine blades. This design aims to protect the FBG sensor while maximizing the strain transfer from the CFRP to the FBG sensor. Strain and temperature experiments showed that the linear correlation coefficient of the experimental CFRP-FBG sensor's central wavelength change-strain evolution curve was above 0.9999, and the repeatability error of the strain sensitivity coefficient was 0.1665%, demonstrating high accuracy and repeatability. Meanwhile, CFRP-FBG was tested in full-size turbine blades in operation, during which time they were subjected to millions of dynamic strain cycles and various loading environments. The results of 11 months of monitoring showed that the CFRP-FBG provides real-time, reliable, and highly accurate strain measurements and can meet the needs of long-term blade strain monitoring.
