It utilizes the changes in the center wavelength of reflected light from various sensors connected in series or parallel along the fiber optic for online temperature monitoring. The sensor part does not require power supply and is not affected by electromagnetic interference. Fiber Bragg grating, as one of the most promising passive optical devices, has been widely used in the field of fiber optic sensing due to its superior characteristics such as anti electromagnetic interference, коррозионная стойкость, low fusion loss, высокая чувствительность, небольшие размеры, and easy distributed measurement. The use of fiber optic gratings for high-temperature safety monitoring has broad application prospects, and the practical research of temperature resistant sensing systems based on fiber optic gratings has always been a hot topic of concern for scholars at home and abroad; Fiber optic grating acoustic emission sensing technology is a new detection technology that combines the advantages of fiber optic grating sensing technology and acoustic emission detection technology. It has shown good development momentum in the field of structural health monitoring.

With the rise and rapid development of various fields of fiber optics, there is an increasing demand for new types of fiber optic devices with higher performance and lower costs, which continuously promotes the development and innovation of fiber optic devices. In this context, fiber Bragg gratings, as a new type of fiber optic device, have received great attention and made continuous progress due to their flexible and variable structural characteristics, as well as good and stable frequency selection characteristics. Fiber Bragg grating is a refractive index distribution formed in optical fibers through methods such as illumination and candle engraving. When light is transmitted in a fiber with this refractive index distribution, it undergoes symmetry, thereby achieving control over phenomena such as reflection and loss during light transmission in the fiber. By utilizing this characteristic, fiber Bragg gratings have been greatly developed and applied in fields such as optical information processing, fiber optic communication, and fiber optic sensing.
