Winding method for high-stability fiber loop with trapezoidal cross section

Abstract

The invention discloses a winding method for a high-stability fiber loop with a trapezoidal cross section. The winding method comprises the following steps: S1) by taking a central point of an optical fiber as a starting point, clockwise winding N turns of first-layer optical fibers on a winding assembly at one end X of the optical fiber; S2) anticlockwise winding N-1 turns of second-layer optical fibers at the other end Y of the optical fiber, wherein the second-layer optical fibers are located on the middle positions of the two optical fibers on the lower layer; S3) anticlockwise winding N-2 turns of third-layer optical fibers at the other end Y; S4) clockwise winding N-3 turns of fourth-layer optical fibers at the end X; and S5) analogizing successively, thereby forming the fiber loop with the trapezoidal cross section. The invention has the beneficial effects that the cross section of the fiber loop is of trapezoidal shape, the overall stability is increased and the winding assembly structure and the fiber loop curing process are simple.

Description

technical field [0001] The invention relates to the technical field of fiber optic gyroscopes, in particular to a winding method of a high-stability fiber optic ring with a trapezoidal section. Background technique [0002] Traditional mechanical gyroscopes and laser gyroscopes contain rotating parts and friction parts, which have short service life, small dynamic range, and high cost. Compared with traditional mechanical gyroscopes and laser gyroscopes, fiber optic gyroscopes are all solid-state, have no rotating parts and friction parts, have long life, large dynamic range, simple structure, light weight, and low cost. In view of many advantages, fiber optic gyroscopes are used in Inertial navigation systems used in military and civilian fields such as aviation, navigation and aerospace are widely used. [0003] The fiber optic ring is the core sensitive component of the fiber optic gyroscope, and its quality directly affects the accuracy and quality of the fiber optic gy...
