Abstract

Pour la mesure de l'indice de réfraction d'un milieu (18), par exemple un liquide ou un gaz, ce système comprend une guide d'ondes (14) présentant un réseau de Bragg brasé (16), dont la réponse spectrale dépend de l'indice de réfraction du milieu, une source lumineuse (20) en vue de provoquer une interaction entre cette lumière avec le réseau, des moyens (22) permettant l'analyse de la lumière ayant interagi avec le réseau, des moyens (24) de récupération du spectre réalisé par des moyens d'analyse spectrale et des moyens (26) permettant la corrélation, à partir du spectre récupéré, la réponse spectrale du réseau avec une valeur de l'indice de réfraction du milieu.
