WebDec 1, 2024 · A traditional tool to have this functionality is the Optical Time Domain Reflectometer (OTDR) which measures the backscatter within a fiber distributed spatially using the time taken to return from an initial light pulse. OTDR use has expanded the long history of Radiation-induced optical attenuation (RIA) investigations. WebFeb 15, 2012 · In this study, we proposed a new concept of optical fiber based radiation distribution measurements with near infrared (IR) emission. Near IR scintillators were attached to the ends of optical fibers, where the fibers were bundled and connected to an N-MOS line sensor or a cooled CCD camera.
WebOptical fibers are circular dielectric wave-guides that can transport optical energy and information. They have a central core surrounded by a concentric cladding with slightly lower (by ≈ 1%) refractive index. Optical fibers are typically made of silica with index-modifying dopants such as GeO 2. WebWe develop a theory for predicting the intensity of Čerenkov radiation generated within the core of a multimode optical fiber by using a ray optic approach and use it to make predictions of the intensity of radiation transmitted down the fiber in propagating modes.

All optical fibers undergo some darkening depending on a number of factors that include: ionization type, optical fiber core glass composition, operating wavelength, dose rate, total accumulated dose, temperature and power propagating through the core. Since attenuation is composition dependent, it is observed that fibers having pure silica cores and fluorine down doped claddings are amongst the most radiation hard fibers.
