Abstract

This paper reports a new optical suppression method of fiber optic gyroscope and its relative intensity noise. Using the optimal design of all fiber devices, the relative intensity noise of light source is suppressed at low cost without changing the circuit and algorithm, and the signal-to-noise ratio of gyroscope is improved. The accuracy of fiber optic gyroscope can be improved by 12%, which is very suitable for the performance improvement of fiber optic gyroscope.
