Paper Abstract
We report an experimental fiber optic gyroscope (FOG) utilizing a 1085-m coil of 8-cm diameter driven with a laser of 10- MHz linewidth, with a record rotation-rate noise as low as 0.2 deg/h/√Hz and a drift below 0.038 deg/h. Simulations and comparison to the measured performance of a similar 150-m FOG show that the noise is limited approximately equally by coherent backscattering and polarization coupling in the sensing coil, and unaffected by the Kerr effect.
