Abstract
A fiber-optic gyro includes a source of light and a coil of optical fiber with multiple turns. The coil is rotatable about an axis of sensitivity and optically couples light from the source to the coil to create counter-propagating light beams within the coil. The counter-propagated light beams produce an output signal indicative of the coil rotation rate, which is fed to a photodetector. The multiple turns of the coil vary in size on both sides of the mid-point of the fiber that forms the coil, and these multiple turns are collapsed in the direction of the axis of the coil.
