Paper Abstract

An experimental investigation is conducted to study the effect of alternate winding techniques in reducing fiber optic gyroscope sensitivity to environmental perturbations caused by time- varying temperature and stress. A stress-induced birefringent polarization-maintaining fiber and an elliptical core fiber are wound under two different winding configurations to experimentally study thermally-induced nonreciprocity in small interferometric fiber optic gyroscope coils. The spools, designed to permit temperature control throughout the fiber pack, are constructed with a thermally-insulating material. Fiber extinction ratio and radial temperature gradient data for the coils are obtained in an environmental control chamber. The experimental data are discussed in this paper. Our results indicate that alternating of the winding configuration has no notable effect on the extinction ratio as expected, however proper winding techniques and efficient coil designs can improve the overall performance of the coil over temperature.
