Abstract

La présente invention concerne des gyroscopes du type dit à laser en anneau >>. Le gyroscope à laser en anneau selon l'invention comporte au moins trois miroirs qui définissent un trajet en forme de boucle fermée pour l'un et l'autre des deux faisceaux lumineux qui se déplacent dans des sens opposés au sein du milieu laser actif dudit gyroscope; ledit gyroscope comporte des dispositifs pour faire vibrer chacun des miroirs sans modifier les longueurs des chemins optiques parcourus par chaque faisceau laser. Application à la mesure des vitesses de rotation, même faibles, avec une grande précision.
