A Coriolis gyro (1') has a first and a second resonator (70 1, 70 2), which are each in the form of a coupled system comprising a first and a second linear oscillator (3 1, 3 2, 4 1 and 4 2), in which case the first resonator (70 1) together with the second resonator (70 2) can be caused to oscillate in antiphase with respect to one another along a common oscillation axis (72). A system which is coupled in this way has the advantage that it is possible to measure the rotation rate and accelerations simultaneously, and that it is insensitive to disturbance influences, for example externally or internally acting vibrations.
L'invention concerne un gyroscope de Coriolis (1') comportant un premier et un deuxième résonateur (701, 702) respectivement conçus en tant que systèmes couplés composés d'un premier et d'un deuxième oscillateur linéaire (31, 32, 41 et 42). Le premier résonateur (701) et le deuxième résonateur (702) sont mis en oscillation de façon opposée le long d'un axe d'oscillation commun (72). De manière avantageuse, un système couplé de cette façon permet de mesurer simultanément des vitesses de rotation et des accélérations et se révèle insensible aux influences parasites telles que par exemple des vibrations provoquées de façon externe ou interne.
