摘要
An open-loop phase-modulated fiber optic gyroscope with a wide dynamic range and linear scale factor is described. The optical Sagnac phase shift is transposed into an electrical phase shift by introducing two phase sensitive detectors and two electronic amplitude modulators with independent carrier frequency from the optical phase modulation. Preliminary experiments show good linearity over a wide dynamic range up to 1000-degrees/s and verifies the theoretical prediction.
