摘要： In a method for producing a component, a first layer composite is first produced, comprising a structured layer and a trench filled with an insulating material. The structured layer is electrically conductive at least in a first region. The trench filled with an insulating material extends outwards from a first surface of the structured layer and is arranged in the first region of the structured layer. The first surface of the structured layer faces a first surface of the first layer composite. The method additionally has the step of producing a second layer composite, which has a first depression in a first surface of the second layer composite, and the step of connecting the first layer composite to the second layer composite. The first surface of the first layer composite adjoins the first surface of the second layer composite at least in some regions, said filled trench being arranged within the lateral position of the first depression. After the first layer composite has been connected to the second layer composite, the thickness of the first layer composite from a second surface of the first layer composite to the depth of the filled trench is reduced. The second surface of the first layer composite lies opposite the first surface of the first layer composite. The method further has the step of producing an active structure in the structured layer, said active structure comprising two second regions which are arranged in the first region of the structured layer and which are mechanically connected to each other in a rigid manner but are electrically insulated from each other by means of the filled trench.

摘要： The invention relates to a method and a switch arrangement for operating a micromechanical capacitive sensor having at least one, and at most two, fixed electrodes (E1, E2) and one differential capacitor formed by a movable central electrode (EO) that can be deflected by an external force, wherein the deflection of said electrode (EO) is measured. The invention provides that a fraction of the force acting on the central electrode corresponding to the electrostatic restorative force be compensated. Under closed-loop operation of the sensor, the selection signal is influenced by a regulator supplementing a restore-crosstalk signal in such a manner that the created capacitive restorative force acts in a compensatory manner against the deflection of the central electrode. Two embodiments of the invention and a measure supplementing said embodiments for optimizing the control are presented.

摘要： Disclosed is a method for determining/compensating the bias errors/random walk errors induced by the light source (1) in fiber-optic Sagnac interferometers using a modulation process for the stochastically independent displacement of the operating point to the points of maximum sensitivity. According to the inventive method, a reference beam is decoupled from the light beam that is emitted by the light source of the interferometer and propagates in the direction of the fiber coil, a reference intensity signal which is proportionate to the intensity of the reference beam is generated, the reference intensity signal is demodulated by using the demodulation pattern used in the rotational speed control loop (7, 13) for demodulating the rotational speed intensity signal that is proportionate to the rotational speed, whereby a demodulated reference intensity signal is obtained which represents a measurement of the bias errors/random walk errors that are to be determined. The reference intensity signal is demodulated in synchrony with the rotational speed intensity signal in such a way that the signal portions of the reference intensity signal and the rotational speed intensity signal, which result from fractions of light simultaneously emitted by the light source (1), are demodulated in an identical manner.

摘要： The invention relates to a method for regulating the operating frequency of the optical multifunctional integrated circuit chip for a fibre-optic gyroscope (FOG 100) which is provided with closed control loop. The inventive method consists, in triggering the input of a main FOG controller (14) and a voltage controlled oscillator (VCO) (12) which determines the clock system of the FOG with the aid of an blanking filter (20), by means of the output demodulated signal of a FOG detector (10) in the form of a actual signal. According to said invention, an additional modulating signal in the form of an analog signal (ζE) is supplied to separate correcting electrodes which are embodied together with the electrodes of a digital phase modulator in the integrated optical circuit chip (MIOC) (11). The inventive method and the particular structural design of the MIOC (11) make it possible to accurately adjust the operating frequency of the FOG

摘要： A device (20) for current measurement, based on a fibre-optic in-line Sagnac interferometer, comprising a double refraction phase modulator (24), for the non-reciprocal phase modulation of two orthogonal polarisation modes of a light beam passing through the interferometer. Said device is characterised in that the phase modulator is a digital phase modulator (24). The advantage of the above is that the phase modulator (24) may be directly digitally controlled, permitting a simplification of a corresponding signal processing or control electronic device (32).

摘要： The invention relates to a method and corresponding circuit for pulse redistribution of pwm sensor output data (pi), for example from inertial sensors. The method is characterized in that the scanning interval (s2) of a data processing device, which processes the output signals of one or more sensors, is independent of the length and of the phase position of the limit cycle (s1) or limit cycles (s1) of the sensor(s). In addition, a range transfer of sensors having different working ranges is possible, irrespective of the scanning interval of the data processing device. As a result, incorrect sensor output data can be easily recognized.

摘要： An electro-optical phase modulator, in particular for use in a fibre-optical gyroscope (FOG), is characterised, as long as the time it takes for the light to make one revolution is made to match the working cycle, in that the same pulse response is ensured in both directions of rotation of the light. For that purpose, the modulation electrodes (13, 14...) are arranged in relation to a common counter-electrode (12) in such a way that the propagation in space and time of the potentials on the modulation electrodes and of the electric fields between the electrodes generates a pulse response which is always symmetrically distributed.
