Abstract
A fiber-optic gyroscope (FOG) whose operation is based on Sagnac effect can be used to detect very small rotation rate. The applications of FOG include inertial navigation, attitude heading, horizon sensing and so on. The FOG is a very sensitive sensor, and any environmental variations may induce the signal errors. Thus, noise suppression is a very important issue for developing FOG.n this thesis, the buildup of a home-made FOG is reported. We tested the performance of different FOG configurations. Our homemade FOG could achieve a stability of 0.1 deg./h. The causes of drift were verified by the experiments. The noise performance comparison of FOGs using SPB and DPB SFSs was also made, and we demonstrated that the FOG using a DPB SFS could have lower noises owing to its broader bandwidth. The angle random walk (ARW) was measured to be as low as 0.0015 deg./h^0.5.
