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