Distributed Fiber-Optic Temperature Sensing using Rayleigh Backscatter
In this work we describe how distributed temperature sensing can be done using Rayleigh scatter.
We present a novel technique for distributed fiber-optic temperature sensing based on measuring the temperature-dependent spectral shift of the Rayleigh backscatter signal along an optical fiber. Swept-wavelength interferometry is used to measure the Rayleigh backscatter.
