چکیده انگلیسی

The research on gyroscopes has lasted for a long time, but there is not a thorough analysis of them. In this paper, a detailed theoretical analysis of fiber ring gyroscope and its gyroscope effect are presented, the performance characteristics of optical resonator gyroscope ranging from transmission function Tfrr, Finesse, Q-factor, the gyro sensitivity, signal noise ratio, random walk to dynamic range are all deduced in detail. In addition, a large number of experiments have been done to verify the deduced theoretical results. The sensitivity of the fiber optic gyroscope is analyzed by simulating the relationship between dQ and turn number of fiber ring, make the conclusion that with the increase of turn number of ring, the resonance depth increased while the dQ value decreased, obtain a high sensitivity of 0.21°/h, random walk of 0.0035°/√h, and Q factor of 8 × 106. Moreover, in the digital frequency locked dual rotation gyro experiments, obvious step effect is observed. And the experimental line of frequency difference is very agreement with the theoretical line. The research provides a good theoretical and experimental basis for the study of gyroscopes.
