    Fiber Bragg Grating Smart Materials

    The fibre Bragg grating (FBG) is an optical sensor recorded within the core of a standard, single-mode optical fibre using spatially-varying patterns of intense UV laser light. Nowadays, smart composite materials embed miniaturized sensors for structural health monitoring (SHM) in order to mitigate the risk of failure due to an overload or to unwanted inhomogeneity resulting from the fabrication process. Optical fiber sensors, and more particularly fiber Bragg grating. 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. This research evaluates the use of embedded Fiber Bragg Grating (FBG) optical sensors as real-time structural health monitoring (SHM) solutions for road pavements. The sensors demonstrate superior sensitivity combined with extended durability features alongside their ability to resist.
