Abstract
Distributed fiber optic sensor includes a composite support tube that closely matches the coefficient of thermal expansion of the optical sensing fiber contained therewithin for applications including but not limited to Rayleigh back-scattering, (OFDR, Optical Frequency Domain Reflectometry), Brillouin frequency shift (BOTDA, Brillouin Optical Time Domain Analysis, BOTDR, Brillouin Optical Time Domain Reflectometry), Raman (Optical Time Domain Reflectometry), DPP-BOTDA (Differential Pulse Pair Brillouin Optical Time Domain Analysis), Dual-Index BOTDA, PCF (Photonic Crystalline Fibers), and dense packed Fiber Bragg Gratings, both time and wave length modulated are described in detail.
