The principle of operation of a 2-D frequency-division multiplexed, fiberoptic gyroscope (FDM-FOG) system is presented under the assumption that the two gyro signals do not interfere with each other. The theory is expanded to include the residual cross-interference effect, which may be minimized by proper choice of modulation depths or frequencies. A 2-D FDM-FOG system is realized with a noise equivalent rotation rate of 0.2°/h (0.25 Hz NEB).
