  • Sample and hold flyback phase control circuit for a null seeking fiber optic gyroscope
    Patent number: 5371594
    Abstract: A flyback phase control circuit for a null seeking fiber optic gyroscope system having an optimal peak phase amplitude includes a sample and hold circuit for sampling the phase difference between the clockwise and counterclockwise optical beams in the differential flyback period; and a compensation circuit responsive to the sampled phase difference for driving the nulling phase modulator voltage ramp generator to maintain the predetermined optimal peak phase amplitude.
