Closed loop fiber optic gyro with shupe effect compensation |
摘要 |
A method and a device for compensating Shupe effect drift errors in a fiber gyro that result from time-dependent temperature changes. A closed loop fiber optic gyro includes a VCO control loop and an evaluation unit that incorporates a model which is dependent on the optical path length of light through the fiber coil. The closed loop gyro is arranged to compensate for temperature-dependent drift changes that result from changes in optical path length.
