Abstract

A closed loop fiber optic gyroscope (FOG) system with hybrid structure is proposed and developed. The structure characteristic of the system and the signal detecting method and the influence of the system from feedback signal are analyzed. This system possesses low loss and long term drift. The 300 deg/s dynamic range and less than 300×10 -6 scale factor error can be realized.
