Abstract:
An optical fiber coil assembly for use in a fiber optic gyroscope, comprising:a bobbin disposed about a longitudinal axis, wherein the longitudinal axis is an axis of rotation about which the bobbin revolves; an optical fiber having a first end and a second end, and characterized by an intermediate point between the first end and the second end, wherein a first section of the optical fiber defined from the intermediate point to the first end is wound around the bobbin in a first rotational direction about the axis of rotation, and a second section of the optical fiber defined from the intermediate point to the second end is at least partially wound around the bobbin in a second rotational direction opposite of the first rotational direction; a reversal of the optical fiber in the second section, such that an end portion of the second section, from the reversal to the second end, is wound around the bobbin in the first direction, along with an end portion of the first section; an epoxy zipper disposed between at least a portion of the first section and the second section of the optical fiber, so as to join the first section and the second section of the optical fiber to form a fiber lead pair; and, an epoxy bridge disposed between at least a portion of the fiber lead pair and the bobbin, so as to secure the fiber lead pair to the bobbin.
