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.
