Abstract

The paper proposes a scheme that utilizes phase-shifted fiber gratings technology to proceed to annual fiber gyroscope detection. As sharpness of resonance and polarization influences, the fineness of annual fiber gyroscope detective sensitivity gets limit. The solution method is to use the phase-shifted fiber grating to compress breathe of frequency. It can enhance sharpness of resonance, improve detective sensitivity and weaken parasitic interference influence. It is proved that phase-shifted fiber gratings play an important role to annular fiber gyroscope detective sensitivity validity and polarization weak influence. The scheme breaks a new path that enhances annual fiber gyroscope performance and predigests detective system.
