ABSTRACT:
In a fiber optic gyro (FOG) with a photo-diode phase detector that produces a detector signal that is supplied to an A/D converter to generate a FOG information signal for use in a signal processor to produce a FOG control signal based on FOG controller equations, the photo-diode out is summed with a feedback signal from the signal processor to reduce a DC offset in the input to the A/D converter.
