Abstract
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 were 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. Simulating the relevance of dQ and turn number of fiber ring, analyzing the frequency difference of two counter transmitted waves (CW and CCW) of the rotated system, 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 0.210/h, random walk of 0.00350/√h, and Q factor of 8×106. Moreover, in the digital frequency locked dual rotation gyro experiments, obvious step effect was 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.
