1. Principle of operation
The implementation of fiber optic gyroscopes is mainly based on the Sagnac theory: the Sagnac effect describes the interference phenomenon of light in a rotating reference system: when light propagates in a closed loop (e.g., a fiber optic ring) in the clockwise and counterclockwise directions, if the system is in a rotating state, the optical paths of the two beams of light show a small time difference, leading to a phase difference. This phase difference is proportional to the rotational angular velocity and can therefore be used to measure rotational motion. This is how fiber optic gyroscopes work.

4. High Accuracy and Stability
The fiber optic gyroscope adopts the advanced Sagnac effect detection technology, which provides high angular velocity measurement accuracy (up to 1°/h or less) and excellent zero-bias stability over long periods of time, ensuring that reliable navigation and attitude control data can still be provided in complex environments.
