Abstract
A fiber optic sensor coil and method of forming a fiber optic sensor coil including a plurality of turns of a first segment of optical fiber wound in a clockwise direction and a plurality of turns of a second segment of optical fiber wound in the counterclockwise direction. The turns of the first segment and of the second segment together forming a plurality of layers of turns of the optical fiber. A restraining ring covers an outermost layer of the plurality of layers of turns of optical fiber. The restraining ring includes a plurality of openings formed therein and provides a compressive force to the plurality of turns of the optical fiber.
