Fiber optic gyroscope modulation amplitude control |
摘要 |
An amplitude reset controller for a resonator fiber optic gyroscope using a feedback loop and modulation to control amplitudes of a serrodyne waveform provided by a serrodyne signal generator at an operation frequency depending on resonance conditions in the resonator. The controller with a single serrodyne signal generator switches between such control at greater rotation rates and the removal of such control at smaller rotation rates, using instead a reference command. Also, a blanking operation mode can be additionally used to eliminate signals controlling the controlled frequency adjustment signal generator operation frequency during phase resets in its output serrodyne signal.
