System to reduce gyroscopic errors with limited power supply quality in a fiber optic gyroscope |
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. |
