ABSTRACT

The various advantages of fiber optic sensing techniques make it attractive to many industrial sensor applications. Fiber Bragg gratings (FBGs) are found in several different types in terms of manufacturing, installation, and application. For FBG sensors, one of the most important sensor parameters to be used to determine a target is the Bragg wavelength of the network. The high capacity in which the FBG sensor scales to measure high voltage levels makes it very suitable for monitoring structural integrity. The properties of FBGs written with fs-infrared radiation the threshold current were studied in both the SM-28 and growth factor of Corning and the pure fiber optic silica nucleus over the long term. Fiber Bragg grating sensors, which are manufactured by means of a pattern obtained by ultraviolet radiation, are assumed to be able to withstand radiation in low-flow nuclear environments, even for extended periods of time.
