Investigation of the System Configuration for Micro Optic Gyros

The re-entrant system configuration of optic gyro was investigated at Tsinghua University for developing the micro optic gyro (MOG). In the system, the bi-directional light beams are circulating in the Sagnac sensing ring (SSR) for many round trips. The feasibility of the proposed system was proved by the test results on the fiber analog experimental setup.
