Brillouin scattering in optical fiber describes the interaction of an electro-magnetic field
(photon) with a characteristic density variation of the fiber. When the electric field amplitude …

A review focused on real world applications of Brillouin distributed fiber sensors is presented
in this paper. After a brief overview of the theoretical principles, some works to face the two …

In this paper we present a Brillouin optical time domain analysis (BOTDA) sensor that takes
advantage of the enhanced characteristics obtained employing self-heterodyne optical …

One of the main goals in fiber optic sensor technology is to multiplex together a high number
of sensors in the same network in order to share expensive terminal equipment and develop …

A transmission sensor able to detect Volatile Organic Compounds (VOCs) has been
developed using optical fiber with Plastic Cladding (PCS). Specifically, 1.5 cm of the …

We demonstrate the extension of the measurement range of Brillouin optical time-domain
analysis (BOTDA) sensors using a distributed Brillouin amplifier (DBA). The technique is …

We study the performance limits of mono-color cyclic coding applied to Brillouin optical time-
domain analysis (BOTDA) sensors that use probe wave dithering. BOTDA analyzers with …

In this study, an optical fiber sensor for the simultaneous measurement of pressure and
position based on a pair of fiber Bragg gratings (FBG) in a clamped beam is proposed. The …

An optical fiber sensor to monitor volatile organic compounds (VOCs) has been developed.
The sensing material used is the organometallic [Au2Ag2 (C6F5) 4 (NH3) 2] n: its optical …

We demonstrate (and are the first to do so) 63 km Brillouin Optical Frequency-Domain
Analysis (BOFDA) for temperature and strain monitoring using a 100 km fiber loop. The use …
