FIBER OPTIC GYROSCOPE WITH REDUCED NON-LINEARITY AT LOW ANGULAR RATES

摘要

The linearity of a fiber optic gyroscope can be improved by dithering thegyroscope's feedback signal. Any undesirable effects introduced by thedithering signal are removed by processing the gyroscope data over an entirecycle of the dithering signal. A further improvement in linearity can beachieved by introducing a compensation signal.
