Abstract

In this paper, the theoretical analysis of hollow-core microstructure fiber for improving the temperature stability of fiber optic gyroscope (FOG) is carried out. The analysis shows that the thermally induced Shupe error can be reduced by a factor of about 23 in theory in a hollow-core microstructure FOG. A FOG prototype is constructed by utilizing a 300mlong 7-cell bandgap-guided hollow-core microstructure fiber, and its temperature stability is compared with that of traditional FOG under the same specification conditions. The experimental results exhibit that the hollow-core microstructure fiber in use can promote the temperature stability of FOG by 2.5 times.
