ABSTRACT:
Single and dual wire gyroscopes determine the orientation and attitude of a device using optical sensing of radiation interrupted by current-carrying, vibrating tensioned wires within a magnetic fields. The tensioned wires vibrate between end nodes within the respective magnetic fields to provide both sustaining oscillatory drives and the sensing of velocity in the directions perpendicular to the respective magnetic fields. Lateral displacements of tensioned wires in directions parallel to the associated magnetic fields are sensed using radiant illumination of the wires and radiation sensing below the wires to provide displacement signals. Precession of wires in vibratory trajectories out of planes perpendicular to respective magnetic fields are controlled by selectively twisting and bending the tensioned wires between mounting ends.
