A kind of precision winding method of optical fiber ring

Abstract

The invention is the field of optical fiber gyroscope fiber optic ring manufacturing technology, which involves a method of precision winding for fiber fiber ring.The method of the present invention includes the following steps: determine the length of the fiber and the structure of the fiber ring; the winding of the winding of the winding; select the applicable partial fiber; the single -mode fiber winding;When the present invention needs to solve the existing optical fiber surrounding method. When a large -length fiber ring is winding, the geometric symmetry of the fiber ring cannot be guaranteed, so that the zero drift of the fiber ring of the fiber ring is too large, which affects the technology of inertia.The problem, by customizing the single -mode fiber and winding workers with special sizes, ensure that the gap between the fiber can be controlled when preserving the optical fiber, and fix the number of fiber turns in each layer.The geometric symmetry of the ring reduces the zero drift of the fiber ring under the temperature of the fiber ring, and improves the accuracy of the inertial gyroscope.

technical field [0001] The invention belongs to the technical field of fiber optic gyroscope fiber ring manufacturing, and in particular relates to a precision winding method for an optical fiber ring. Background technique [0002] Temperature performance has always been a key indicator of fiber optic gyroscope engineering. Among the various components of the fiber optic gyroscope, the influence factor of the fiber optic ring on the temperature performance of the fiber optic gyroscope can reach 90%. For the fiber optic ring, its internal stress state and geometric symmetry directly determine the temperature characteristics of the fiber optic ring. How to suppress the non-reciprocity of the optical path induced by temperature is the most critical research content in the fiber optic gyro technology. Generally, the optical fiber ring is made of polarization-maintaining optical fiber. Therefore, the winding precision must be guaranteed during the winding process of the optical ...
