Abstract
Direct measurement of Sagnac phase shift from an open-loop, all-fiber-optic gyroscope using signal processing is described. The photodetector output from a phase modulated gyro is amplitude modulated at the phase modulation frequency to transpose the optical phase shift into a low frequency electronic phase shift, which is measured using a digital time interval counter. A wide dynamic range and linear scale factor are demonstrated using this approach.
