Title (EN) ENHANCING FUNCTIONALITY OF REFLECTOMETRY BASED SYSTEMS USING PARALLEL MIXING OPERATIONS
(FR) AMÉLIORATION DE LA FONCTIONNALITÉ DE RÉFLECTOMÉTRIE SUR LA BASE DE SYSTÈMES UTILISANT EN PARALLÈLE DES OPÉRATIONS DE MÉLANGE
Abstract: front page image
(EN)A method for estimating a parameter includes: generating an optical signal, the optical signal modulated via a modulation signal; transmitting the modulated optical signal from a light source into an optical fiber, the optical fiber including a plurality of sensing locations disposed along the optical fiber and configured to reflect light; receiving a reflected signal including light reflected from the plurality of sensing locations; and combining, in parallel, each of a plurality of reference signals with the reflected signal to estimate a value of the parameter.
(FR)L'invention concerne un procédé d'estimation d'un paramètre consistant à générer un signal optique modulé par un signal de modulation, à transmettre le signal optique modulé d'une source optique à une fibre optique, la fibre optique comprenant une pluralité d'emplacements de détection situés le long de la fibre optique et conçus pour réfléchir la lumière, à recevoir un signal réfléchi comprenant la lumière réfléchie à partir de la pluralité d'emplacements de détection, et à combiner, en parallèle, chacun des signaux de référence avec le signal réfléchi pour estimer une valeur du paramètre.
