Home / 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.
