We describe a digital integrating fiber-optic gyroscope with a microprocessor-based phase tracker, using an open-loop configuration. The Sagnac phase shift is electrically compensated by a phase generated in the microprocessor-based system. Different from analog schemes, this phase tracker is based on software generation of sine- and cosine-dependent compensating functions that are deduced from integrated interferometric output of gyroscope using dynamic phase modulation. Computer simulation has shown that this scheme may provide wide- dynamic-range sensing with an open loop fiber gyroscope. Potentially a group of fiber optic gyroscopes with such a phase tracker may be interfaced directly to navigation systems.
