摘要： A fiber optic gyroscope includes a light source, an optical coupler in optical communication with the light source, with the optical coupler configured to receive an optical signal from the light source, an optical modulator in optical communication with the optical coupler, and a fiber optic coil in optical communication with the optical modulator. A demodulator is configured to receive an optical signal from the optical coupler and convert the optical signal to an electrical signal. A loop closure electronics module is configured to receive the electrical signal from the demodulator. A bias modulator is responsive to an output from the loop closure electronics module and is configured to output a modulation signal to the optical modulator. A first crosstalk filter network is operatively coupled to the demodulator, and a second crosstalk filter network is operatively coupled to the bias modulator.

摘要： One embodiment is directed to a power supply for a fiber optic gyroscope that comprises at least one main power supply, at least one demodulator local power supply to operatively couple the main power supply to a demodulator included in the fiber optic gyroscope, and at least one modulator local power supply to operatively couple the main power supply to a bias modulator included in the fiber optic gyroscope. The demodulator local power supply comprises a first current source to source current to the demodulator and a first shunt regulator coupled across a load associated with the demodulator. The modulator local power supply comprises a second current source to source current to the bias modulator and a second shunt regulator coupled across a load associated with the bias modulator.
