Patent ID: 8077321

Claim:
A fiber optic gyroscope, comprising: an optical coupler in optical communication with and configured to receive an optical signal from a light source; an optical modulator in optical communication with the optical coupler; a fiber optic coil in optical communication with the optical modulator; a demodulator configured to receive an optical signal from the optical coupler and convert the optical signal to an electrical signal; a bias modulator configured to output a modulation signal to the optical modulator; at least one main power supply; a demodulator local power supply operatively coupled to a first shunt regulator, wherein the demodulator local power supply feeds the first shunt regulator with a current source to operatively couple the main power supply to the demodulator; and a modulator local power supply operatively coupled to a second shunt regulator, wherein the modulator local power supply feeds the second shunt regulator with a current source to operatively couple the main power supply to the bias modulator.
