Abstract: A method for operating a fiber optic gyroscope to measure angular velocity uses a closed-loop modulation scheme. Two-state modulation voltages are applied to an optical modulator and continuously adjusted to maintain a null difference between corresponding demodulated voltages from a photodetector. If one of the modulation voltages reaches a threshold voltage, the continuous nulling adjustment is interrupted briefly while the two-state modulation voltages are reset to values that correspond to relative phases of ?/2 and ??/2 when the gyroscope is stationary, then the continuous adjustment is resumed. This reoccurring resetting, while the gyroscope accelerates or decelerates, substantially increases the dynamic range over which the gyroscope can precisely measure angular velocity.
