Abstract

Phase modulation is studied with regard to high stability, low distortion coefficient, and minimum parasitic modulation effects for the case of a gyroscope of 1 deg/hour performance based on normal birefringent single-mode fiber. Signal processing involves both a novel modification of the optical feedback to compensate for the rotation-caused Sagnac phase shift, as well as a simulation of the optical interferometer output for periodic zero rotation rate adjustment and scale factor calibration.
