Abstract: The control system for a fiber-optic gyroscope comprises a phase modulator for modulating a phase of a light signal and a control unit for producing a control signal, by the magnitude of which the phase is modulated and which is fed to the phase modulator. Moreover, the control system comprises an integration unit for determining an integral value of an integral over an input signal. Here, the control signal assumes a first value or a second value depending on the integral value.

Abstract: The invention relates to a control system (100) for a fiber optic gryoscope, comprising a phase modulator (110) for modulating a phase of a light signal (115) and a control unit (120) for producing a control signal (125), by the value of which the phase is modulated and which is fed to the phase modulator (110). The control signal changes statistically and does not have an average value.

Abstract: The bias error in a fiber optic system comprising a fiber optic gyroscope can be determined by determining of at least two different values for rotation rate by an evaluation unit of the fiber optic gyroscope for almost constant rotation rate applied to the fiber optic gyroscope and/or can be reduced by a linear combination of the at least two different values for the rotation rate. A fiber optic system that is suitable for carrying out this method comprises besides the fiber optic gyroscope a control device that is configured to control at least one element of the fiber optic gyroscope such that at least two different values for the rotation rate are determined by the evaluation unit of the fiber optic gyroscope for almost constant rotation rate applied to the fiber optic gyroscope.

Abstract: A fiber-optic Sagnac interferometer in a rotation rate sensor comprises a multifunctional integrated optical chip (MIOC) with a MIOC transfer function. A digital filter is connected upstream to the multi-functional integrated optical chip, whose filter transfer function corresponds basically to the inverse MIOC transfer function such that the MIOC transfer function is compensated by the filter transfer function. Corresponding coefficients of the filter transfer function may be determined in a main control loop.

Abstract: In the case of a fiber-optic Sagnac interferometer, the output of an analog/digital converter and thus output signals processed in a main control circuit as well as a phase resetting signal for a phase modulation encompass a first word width. An input of a digital/analog converter and thus a resetting signal, which acts on the phase modulator, encompasses a second word width, which is smaller than the word width, with which the resetting and modulation signal is computed. A residual value signal comprising a third word width, which can be added to the output signal of the analog/digital converter via an adder, is obtained from the surplus, low-value bits.
