[0003] However, at present, evaluation devices that are compatible with multiple types of optical fiber rings at the same time need to adjust the circuit board, the position of each optical device, and the fiber routing path of each optical device when replacing different types of optical fiber rings. The corresponding optical fibers between the waveguide and the fiber coupler, the fiber coupler and the PIN-FET component, the fiber coupler and the light source are re-spliced, the evaluation consistency is poor, the operation process is complicated, the workload is heavy, and the production efficiency is low

The invention relates to an optical fiber ring evaluation module and an evaluation system. The fiber arrangement of optical fibers of a to-be-evaluated optical fiber ring is reasonable in structure, so that leading-out optical fibers of the optical fiber ring and leading-out optical fibers of each optical device can be arranged reasonably, and extrusion interference cannot be generated between theleading-out optical fibers. The main structure comprises a supporting frame and an optical fiber ring unit; the optical fiber ring unit comprises a 2*2 optical fiber coupler, a Y wave-guide, a base and an upper cover; the base is fixed on the supporting frame, the upper cover is buckled on the base, and a fiber outlet hole is formed in the base and the upper cover in a buckling mode; the base isround, an annular protrusion is arranged on the outer edge of the base, and an annular groove is formed in the position, close to the annular protrusion, in the base; and the to-be-evaluated optical fiber ring is installed in the center of the base, and the 2*2 optical fiber coupler and the Y wave-guide are installed between the annular groove and the to-be-evaluated optical fiber ring.
Description
technical field [0001] The invention relates to an optical fiber gyroscope, in particular to an optical fiber ring evaluation module and an evaluation system. 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. Fiber optic gyroscopes mainly include fiber optic rings, optical devices (Y waveguides, fiber optic couplers, light sources, PIN-FET components), circuit boards and structural parts, among which fiber optic rings are the core components of fiber optic gyroscopes, and their performance directly affects the performance of fiber optic gyroscopes. Accuracy, fiber optic ring evaluation is a key link in the production process of fiber optic gyroscopes. [0003] However, at present, evaluation devices that are compatible with multiple types of optical fiber rings at the same time need to adjust the cir...
