APPAREIL DE MESURE DE ROTATION |
摘要 |
The device sets in vibration two sensors (161, 162) of radial elongation of the mechanical resonator (10) in the directions of application of forces by transducers (141,142) with angular spacing of 45 degrees . The sensors provide signals modulated at the vibrational frequency to an electronic circuit (12) which drives the transducers to sustain the vibration at constant amplitude. The time-quadrature component of the vibration is cancelled and the drive to the transducers contains a precession control component. An error is calculated from knowledge of this control and measurement of the rate of rotation of the resultant vibrational field.
