Abstract

La présente invention concerne un système optomécanique de mesure de pression permettant de mesurer un niveau de pression ambiante, le système comprenant une fibre ayant une première extrémité de fibre et une seconde extrémité de fibre, une cavité optomécanique étant montée au niveau de la première extrémité de fibre et composée d'un premier élément de membrane et d'un second élément de membrane espacés l'un de l'autre, le premier élément de membrane étant en contact avec la première extrémité de fibre, au moins un dispositif de génération de faisceau de lumière couplé à la seconde extrémité de fibre et structuré pour produire et diriger des faisceaux de lumière, chaque faisceau de lumière ayant une certaine fréquence optique, par l'intermédiaire de la fibre sur la cavité optomécanique, et un élément de détection de lumière couplé à la seconde extrémité de fibre, le ou les dispositifs de génération de faisceau de lumière étant structurés pour diriger un premier faisceau de lumière ayant une première fréquence optique sur la cavité optomécanique, le premier faisceau de lumière étant modulé à une fréquence de modulation à l'intérieur d'une largeur de bandes d'une fréquence de résonance mécanique du second élément de membrane, le ou les dispositifs de génération de faisceau de lumière étant structurés pour diriger un second faisceau de lumière ayant une seconde fréquence optique sur la cavité optomécanique; et l'élément de détection de lumière étant structuré pour détecter une partie du second faisceau de lumière réfléchi par la cavité optomécanique et pour déterminer la pression ambiante autour de la cavité optomécanique sur la base d'un changement de l'amplitude d'oscillation du second élément de membrane.
