Fiber Bragg Grating Temperature Sensing Linkage
There are two principal methods of distributed strain or temperature sensing; (i) monitoring the Brillouin or Raman light backscattered from an optical fiber (DSS/DTS), or (ii) measuring the wavelengths reflected from an array of multiple fibre Bragg gratings (FBGs). Fiber Bragg grating (FBG) sensors have emerged as advanced tools for monitoring a wide range of physical parameters in various fields, including structural health, aerospace, biochemical, and environmental applications. Temperature measurement is crucial for many industrial processes and monitoring tasks. Most of these measurement tasks can be carried out using conventional electric temperature sensors, but with limitations.

Fiber Bragg Grating Temperature Control Principle
This article explains the principle of Fiber Bragg Grating (FBG) sensors based on the fundamental concept of "reflection and interference of light waves," including the principles of temperature measurement, stress measurement, and strain measurement using FBGs. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a.

Fiber Bragg grating array deformation monitoring
In the deformation monitoring of steel structure engineering, the fiber Bragg grating flexible sensor (FBGFS) is an emerging technology widely used in various monitoring fields, with advantages such as sensitivity, stability, and resistance to electrical interference . This review presents a comprehensive analysis of fiber Bragg grating (FBG)-based sensing technologies as a promising solution for deformation monitoring in space infrastructure. In this paper, a monitoring method of structural vibration deformation based on Fiber Bragg Grating (FBG) strainmeter array and accelerometer array is proposed for two different cases of whether the structure surface can be directly pasted with FBGs.
