Paper Abstract

A resonator micro optic gyro (RMOG) with the proposed FPGA-based digital processor is set up. The double phase modulation technique is applied to achieve high total carrier suppression. Rotation tests from ±0.1 °/s to ±5 °/s are tested, where the processing circuit of RMOG is implemented by the instruments. The rotation test over a range of ±550 °/s has been successfully obtained with all the processing circuit implemented in FPGA. To the best of our knowledge, these results are the best results of RMOG ever demonstrated in silica resonator with the ring length as short as 7.9 cm.
