Abstract
A symmetric fiber optic sensing coil for use in a rotation sensing device such as a gyroscope. The coil comprises a plurality of turns of a continuous strand of orthogonally wound fiber optic material. The coil may comprise either dualpole or quadrupole symmetry and may be formed on a spool having at least one aperture in each of its circular flanges. The symmetric sensing coil is minimally affected by environmental factors such as temperature, vibration and magnetic fields that can otherwise produce measurements that are indistinguishable from sensed rotation.
