Distributed optical fiber sensors (DOFS) can measure lots of sensing parameters distributed along the fiber under test (FUT) such as strain, stress, vibration, temperature, 3D shape, flow rate, refractive index, magnetic field, radiation, gas, etc. DOFS have many attracting features such as light weight, small size, non‐corrosive, immunity to electromagnetic interference, harsh environment suitability, large scale, and high sensing density, which are very useful for many sensing applications [1].
Several DOFS technologies have been developed based on the measurement of intrinsic backscattering, including Raman, Brillouin, ...
