Abstract

The term “Distributed fiber-optic sensing” covers a family of technologies that have complemented the toolbox of industrial monitoring during the past years. Within this family, the most relevant members are Distributed Temperature sensing (DTS), making use of Raman scattering along the fiber; Distributed Acoustic Sensing (DAS), which records a dynamic profile of Rayleigh backscattering; and Distributed Temperature and Strain Sensing (DTSS), which exploits the nonlinear optical effect known as Brillouin scattering. Unlike DAS, which puts its sensing focus on momentarily events, Brillouin DTSS is a powerful technology when it comes to quantitative analysis of static structural behavior, providing a long-term stable, continuous profile of the sensing fiber’s inherent strain and temperature.
