Abstract

A relative intensity noise suppression scheme for high-precision fiber optic gyroscope is designed. The technical scheme of this letter can effectively suppress the influence of RIN on the detection accuracy of high-precision fiber optic gyroscope, and has simple structure and low cost. By adjusting the modulation depth to make the two light intensities match all the time, the fiber optic gyro can maintain the optimal suppression effect on the relative intensity noise and improve the gyro accuracy.
