▎ 摘　　要

NOVELTY - The method involves winding a layer of graphene heat conducting film (3) on an optical fiber surrounding ring tool as a bottom layer heat conducting layer, and using multi pole symmetrical winding optical fibre ring. The optical fiber winding layer of the graphene heat-conducting film is wound, and then winding of a periphery winding layer as a top layer heat conducting layer is performed. The periphery winding is wound as a top-layer heat conducting membrane after finishing the winding of the optical fiber circular ring. USE - Method for improving temperature performance of optical fiber ring used in inertial navigation system and missile weapon system. Can also be used in optical fiber gyroscope. ADVANTAGE - The method adopts the graphene heat conducting film with high heat conductivity coefficient, which has good flexibility can be used as the heat conducting layer into the optical fiber ring, effectively improving the optical fibre ring heat conducting coefficient, reducing the temperature gradient between the optical fibers layer, and improving the temperature performance of the fiber ring. The method is doped with graphene in the fiber surrounding tape surrounding the operation is more convenient, and the thickness of the graphene is easier to control than the graphene doping concentration. The graphene-based fiber ring temperature performance improvement method solves the problem that the graphene volume ratio is too high, which cannot improve the fiber around the tape surrounding heat-conducting coefficient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an optical fiber ring based on graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the method.
