Rayleigh, Brillouin and Raman scatterings in fibers result from the interaction of photons with
local material characteristic features like density, temperature and strain. For example an …

Fiber-optic distributed sensing, employing the Brillouin effect, is already a commercially
available measurement technique for the accurate estimation of the static strain/temperature …

Brillouin optical time-domain analysis (BOTDA) requires frequency mapping of the Brillouin
spectrum to obtain environmental information (eg, temperature or strain) over the length of …

A thorough analysis of the key factors impacting on the performance of Brillouin distributed
optical fiber sensors is presented. An analytical expression is derived to estimate the error …
