Abstract

This paper describes a closed-loop fiber optic gyroscope, emphasizing the control tracking circuit to realize the closed-loop operation. This control tracker consists of reversal counters with the characteristic of folded binary codes. The experimental results show that the control tracker can be successfully used in the fiber optic gyroscope with a gated phase modulation approach and provides a practical way to implement momentarily the closed-loop operation of the gyroscope.
