Fundamentals and applications of optical fiber Bragg grating sensors to textile structural composites

摘要: In this paper, a review is given on the principles of optical fiber Bragg grating (FBG) sensors and their applications in textile structural composites (TSCs). As class novel all-fiber based components, FBG consists spatially periodic modulation refractive index along short length an fiber. are immune to electromagnetic interference, small size, easily embedded variety composite materials without compromising host structures. They can be mass-produced low cost unique sensing strategies for absolute wavelength coding multiplexing. The intrinsic division multiplexing localized abilities FBGs most important advantages as they provide effective means monitoring physical parameters single path. This ability determine quantitatively internal distributions within TSC integrated with such has been demonstrated by number workers will lead better understanding relationship between structure properties.
