Abstract

Une méthode et un système permettant la mesure simultanée de caractéristiques de déformation et de température d'un objet comprennent la fixation à l'objet d'une paire de fibres optiques ayant des indices de réfraction différents, les fibres étant connectées ensemble à au moins une de leur extrémité, et en orientant une lumière laser dans au moins une extrémité des fibres. La fréquence de Brillouin de chacune des fibres est mesurée et les caractéristiques de déformation et de température sont calculées en fonction des coefficients de déformation et de température et des fréquences de Brillouin mesurées des fibres.
