摘要

Currently, using optical fibers as sensors is gradually spreading beside their usage in communicationsystems as low-loss transmission media. The gyroscope is one of the basic devices used for accurate directionforecast, location and position control. The interferometric optical fiber gyroscope (IFOG) is the most preferredgyroscope type in various military and commercial applications, especially in navigation systems. In this paper,theoretical background of angular displacement sensing with phase modulating IFOG has been described, phasemodulating open and closed loop IFOG structures developed to overcome performance problems occurring inthe basic IFOG structure have been analyzed, IFOG performance characteristics have been mentioned andSagnac phase difference simulations based on terrestrial navigation applications have been performed. In thesimulations, variations of Sagnac phase difference with angular velocity for different fiber lengths, variations ofphotodetector output power and output signal with Sagnac phase difference have been investigated. The impor-tant points where the simulation results are in good agreement with or separate from the results obtained in prac-tical applications have been emphasized.
