Temperature testing device for optical fiber ring of optical fiber gyroscope

The utility model discloses a temperature testing device for an optical fiber ring of an optical fiber gyroscope. The temperature testing device comprises a lower cover, an adhesive transition plate, an upper cover, a Y waveguide optical integrator and a temperature sensor, wherein the lower cover and the upper cover form a shell mechanism structure for placement, so that the requirements of various temperature environments are met, and meanwhile, the influence of the thermal design of the shell of the fiber-optic gyroscope on the temperature performance of a tested fiber-optic ring can be reflected; the design of the adhesive transition plate improves the convenience of installation and disassembly of the tested optical fiber ring, a tool is in contact with the adhesive transition plate when the tested optical fiber ring is disassembled in a narrow space, direct contact between the tool and the tested optical fiber ring is avoided, and thus the tested optical fiber ring is prevented from being damaged during
