摘要： A spin rate measurement device for rotating missiles. Preferably, three micromechanical spin rate sensors whose three spatial axes are aligned at right angles to one another, each of which is designed to be excited, read and reset capacitively, are arranged on a single platform that can be rotated by means of a servo loop for rotation decoupling. The spin rate measurement device is distinguished by high bias and scale factor stability that can be checked at any time.

摘要： A small modulation current is applied to the light source of a Sagnac-type fiber optic gyroscope to increase accuracy and/or stability of scale factor (open loop configuration) and to reduce bias errors and random walk (closed-loop configuration). The phase and amplitude of the modulation current are controlled through a control circuit whose reference is picked off at a first beamsplitter in series with the light source. In such a way, light emitted from the light source into the interferometer contains no modulation. The elimination of modulation removes a source that would otherwise cause deterioration of gyroscope stability resulting from light returning from the interferometer or due to electrical interference, thus limiting measurement accuracy.

摘要： In a method for quadrature-bias compensation in a Coriolis gyro, whose resonator (1) is in the form of a coupled system comprising a first and a second linear oscillator (3, 4), the quadrature bias of the Coriolis gyro is determined. An electrostatic field is produced by variation of the mutual alignment of the two oscillators (3, 4) with respect to one another, with the alignment/strength of the electrostatic field being regulated such that the determined quadrature bias is as small as possible.

摘要： A Coriolis gyro includes a first and a second resonator, each in the form of a coupled system comprising first and second linear oscillators. The first resonator can be caused to oscillate in antiphase with respect to the second resonator along a common oscillation axis. A system coupled in this way has the advantage that it is possible to measure rotation rate and acceleration simultaneously, with insensitivity to disturbances (e.g., externally or internally acting vibrations).

摘要： An accelerometer having a micromechanical pendulum, a capacitive pick off and a control loop reset by electrostatic forces and, in a time sequence, applies a resetting voltage between the pendulum and two electrodes spaced apart on opposite sides of the pendulum. The control loop is designed such that, firstly, no charge difference flows via the pendulum and a force of identical magnitude thus acts on both sides of the pendulum. Secondly, when a pendulum deflection occurs in response to a voltage difference, the time durations of the respectively applied voltage pulses are impeded in accordance with the acceleration. The simultaneous control of two components results in the control bias tending essentially to zero. The capability of temporarily switching to detection of the total charge as the control variable also allows control of the scale factor of the accelerometer.
