Abstract

The invention relates to a fiber-optic gyroscope, in particular to a graphene-based fiber-optic ring temperature performance improvement method and a fiber-optic ring, which are used for solving the problem that the heat conductivity coefficient of fiber-optic ring surrounding glue cannot be improved due to too high volume ratio of graphene. According to the graphene-based method for improving the temperature performance of the optical fiber ring, a graphene heat conduction film with a high heat conduction coefficient is adopted as a heat conduction layer to be added into the optical fiber ring, so that the heat conduction coefficient of the optical fiber ring is effectively improved, the temperature gradient between optical fiber layers is reduced, and the temperature performance of the optical fiber ring is improved; the operation is simpler and more convenient, and the thickness of the graphene heat-conducting film is easier to control. Meanwhile, the invention also provides a graphene-based optical fiber ring.

Description

technical field [0001] The invention relates to an optical fiber gyroscope, in particular to a graphene-based method for improving the temperature performance of an optical fiber ring and the optical fiber ring. Background technique [0002] Fiber optic gyroscopes have the advantages of shock resistance, high sensitivity, long life, large dynamic range, and short start-up time, and have been widely used in inertial navigation systems. Affected by the heating of itself and the inertial navigation system, the fiber optic gyroscope has a process of rapid temperature rise from power-on to temperature stabilization. During this process, the zero position fluctuates due to the Shupe effect of the fiber optic ring and changes in stress distribution, so that the fiber optic gyro There is a warm-up time of more than tens of minutes, which greatly affects the rapidity of the inertial navigation system and even the missile weapon system. [0003] The temperature problem is one of the ...
