Paper Abstract

A closed-loop resonator integrated optic gyro (RIOG) scheme based on triangular wave phase modulation is proposed. Only one integrated optic modulator (IOM) is employed. Triangular wave is applied on the IOM to modulate the passing light wave, and the feedback serrodyne wave is superimposed upon the triangular wave to compensate the resonant frequency-difference. The experimental setup is established and the related measurements are performed. The results show that the proposed scheme can realize the closed-loop RIOG employing an IOM, which has the advantage of miniature size. A bias stability of 0.39 deg/s (10 s integration time) over 1 hour is achieved. Moreover, good linearity and large dynamic range are also experimental demonstrated.
