This review provides a comprehensive overview of FBG sensor technology, focusing on their operating principles, key advantages such as high sensitivity and immunity to electromagnetic interference, and common challenges like temperature-strain cross-sensitivity and the high cost of. 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. This review provides a comprehensive overview of FBG sensor technology. Including: various of Fiber Bragg Gratings (FBG or Fiber Optic Grating), FBG sensors (Temperature, Strain, Displacement, Stress, Vibration, Liquid level, Shape, etc. ), FBG demodulators (FBG Interrogators), and application experience of the above products in different industries. Researchers have gained enormous attention in the field of fiber Bragg grating (FBG)-based sensing due to its. Today, no one doubts that fiber Bragg gratings (FBGs) have become the most used tool for measuring various physical parameters, the structural integrity of engineering systems, and the biological activity of living systems. Classical approaches to measurements based on temperature and mechanical. An FBG Sensing System comprises three discrete sub-systems: i) A network of fibre Bragg grating sensors or transducers embedded within or attached to the structure being monitored ii) An FBG Interrogator, an optoelectronic unit which illuminates the sensor network and records the optical reflection. In the vast realm of optical fiber sensing, where precision and innovation converge, Fiber Bragg Gratings (FBGs) stand as luminaries, casting their influence across myriad applications.
