    Abstract: A system for rotationally biasing a fiber optic gyroscope includes a fiber optic gyroscope assembly comprising a light source that emits an optical signal, an optical coupler in optical communication with the light source, and a fiber optic coil in optical communication with the light source. The fiber optic coil receives the optical signal through the optical coupler and imparts a phase shift proportional to rotation. A rate sensing detector in optical communication with the fiber optic coil receives the optical signal from the fiber optic coil through the optical coupler. A motor coupled to the fiber optic coil applies a periodic rotation to the fiber optic coil to impart a biasing phase modulation to the optical signal. A signal processing unit is coupled to the fiber optic gyroscope assembly and the motor. The signal processing unit converts a measured intensity of the optical signal to rotation rate data.

    Abstract: Systems and methods for dynamic bias offset operation in RFOGs are provided. In certain embodiments, an RFOG system includes a fiber optic resonator; laser sources that launch first and second optical beams into the fiber optic resonator in opposite directions; a first servo loop configured to lock the first optical beam to a resonance frequency, the first servo loop including a modulator that modulates the first optical beam at a first resonant tracking frequency; a second servo loop configured to lock the second optical beam frequency, on average, to a resonance frequency, the second servo loop including a modulator that modulates the second optical beam at a second resonant tracking frequency, wherein the second optical beam is further modulated by a modulation frequency; and a filter configured to attenuate signals that result from the interference of the first and second optical beams.
