Reduction of fiber optic gyroscope vibration and temperature-ramp sensitivities by controlling coil geometrical parameters

摘要

A method for providing an optical fiber coil having reduced bias vibration and bias temperature-ramp sensitivity by controlling and adjusting coil geometrical factors including the coil potted length, the adhesive layer thickness, the number of turns per layer, the number of layers and the way the winding is terminated. The windings may be terminated to form the coil as a complete quadrupole, a diapole, an incomplete quadrupole or an incomplete diapole. By adjusting geometrical factors of the coil design, a coil for which the residual net Shupe bias is negligible is obtained.
