Abstract

Fiber-optic frequency-modulated continuous-wave (FMCW) Sagnac gyroscopes1 can solve the problems of zero-sensitivity point, inaccurate phase calibration, ambiguous shift direction determination and ±π/2 phase shift restriction, and reduce the size and weight of the gyroscopes because they do not use bulk phase modulators or bulk frequency shifters. However, because fiber-optic FMCW Sagnac gyroscopes have to be unbalanced in order that the beat signal with a proper frequency can be obtained, they may have a non-reciprocal phase drift if the surrounding parameters (such as temperature) change. This paper reports a differential single-mode fiber FMCW Sagnac gyroscope, which can remove the non-reciprocal phase drift, and therefore provide a better long-term stability.
