    • A method for characterizing Coriolis gyros, in the case of which the interaction of the system comprising force transmitters, a mechanical resonator and excitation/readout vibration pick-offs is represented as a discretized, coupled system of differential equations. The variables of the system of equations represent the force signals supplied by the force transmitters to the mechanical resonator and the readout signals produced by the excitation/readout vibration pick-offs. The coefficients of the system of equations contain information relating to the linear transformation which maps the force signals onto the readout signals. The coefficients are determined by measuring force signal values and readout signal values at different instants and substituting them into the system of equations. The system of equations is numerically resolved in accordance with the coefficients, and the coefficients are used to infer undesired bias properties of the Coriolis gyro which corrupt the rate of rotation of the Coriolis gyro.

    • A method for compensation of the zero error of a Coriolis gyro. The frequency of the read oscillation is modulated. The output signal from a rotation rate control loop or quadrature control loop for the Coriolis gyro is demodulated in synchronism with the modulation of the frequency of the read oscillation to obtain an auxiliary signal. The auxiliary signal is a measure of the zero error. A compensation signal is produced and passed to the input of the rotation rate control loop or quadrature control loop, with the compensation signal being controlled such that the magnitude of the auxiliary signal is as small as possible

    • In a method for electronic tuning of the frequency of the read oscillation to the frequency of the stimulation oscillation in a Coriolis gyro (1′) according to the invention, the resonator (2) of the Coriolis gyro (1′) has a disturbance force applied to it such that the stimulation oscillation remains essentially uninfluenced, with the read oscillation being changed such that a read signal which represents the read oscillation contains a corresponding disturbance component. The frequency of the read oscillation is controlled such that the phase shift between the disturbance signal and the disturbance component which is contained in the read signal is a minimum.

    • A rotation rate readout method employing a passive optical resonator. The ring resonator is operated at approximate resonance in reflection and rotation rate-dependent phase shifts are detected, in particular as first harmonics, in the resonator. Two partial light beams are first frequency shifted by equal and opposite amounts, such frequency shift being modulated. Light components coupled out of the resonator pass through a mode filter in the opposite direction and are detected as an interference signal by an opto-electronic converter. The latter signal is demodulated with respect to the modulation frequency or its harmonics and the rotation rate signal obtained therefrom. Self-compensation of the optical and electronic readout systems may be attained by periodic brief and strong damping of the ring resonator. In contrast with known methods wherein two channels are separately processed and two mode filters required, the interference signal is processed in accordance with the invention requiring only a single mode filter.
    • 采用无源光谐振器的旋转速率读出方法。 环形谐振器在反射中以近似谐振工作,并且在谐振器中检测到与速率相关的相移,特别是作为一次谐波。 首先将两个部分光束频移相等和相反的量,这样的频移被调制。 耦合在谐振器外的光分量通过相反方向的模式滤波器,并被光电转换器检测为干扰信号。 后一个信号相对于调制频率或其谐波和从其获得的转速信号进行解调。 光学和电子读出系统的自补偿可以通过环形谐振器的周期性短暂和强阻尼来实现。 与已知的方法相反,其中两个通道被单独处理并且需要两个模式滤波器,根据本发明处理干扰信号,仅需要单模滤波器。
