PHASE MODULATION STABILIZATION METHOD OF FIBER OPTIC GYROSCOPE USING CORRECTING ERROR AND FIBER OPTIC GYROSCOPE

摘要

The present invention relates to a phase modulation method of an optical fiber gyroscope and an optical fiber gyroscope, and a phase modulation method of an optical fiber gyroscope provides a phase modulation signal to the light such that the light generated from the light source is modulated in the first and second phase sections. Adding the light, separating the light and advancing the separated light in different directions so as to have a phase difference generated by the rotation of the gyroscope; To the first and second output periods corresponding to the first and second phase sections, respectively, and the difference between the first and second output average values. Correcting a phase modulation amplitude of the phase modulation signal. Through this, the present invention stabilizes the phase modulation amplitude in the optical fiber gyroscope.;Fiber Optic, Gyroscope, Phase Modulation Amplitude
