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. A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. Our optical fibers offer high sensing multiplexing capability on the smallest possible footprint, while maintaining mechanical and. IDIL manufactures single FBG sensors and FBG array sensors for continuous monitoring of temperature, strain, and various physical and chemical parameters. These include low loss relative to fiber length, immunity to electromagnetic and radio frequency interference, compact size and weight, and safe operation in hazardous.
