Distributed Fiber Bragg Grating Sensing Technology
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). Distributed acoustic sensing (DAS) systems have been widely employed in oil and gas resource exploration, pipeline monitoring, traffic and transportation, structural health monitoring, hydrophone usage, and perimeter security due to their ability to perform large-scale distributed acoustic. 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. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a. Fiber Bragg grating (FBG) optical sensors have emerged as a leading technology for distributed strain and temperature measurement. However, each method has its.
