Fiber optic gyroscope with a reduced non-linearity at low angular velocity

摘要

(57) linearity SUMMARY fiber optic gyroscope can be improved by dithering the feedback signal of the gyroscope. Unwanted effects introduced by the dithering signal is removed by treating the gyroscope data over the entire cycle of the dithering signal. By directing a compensation signal, it is possible to further improve the linearity.
