Winding skeleton of double-column type optical fiber ring

Abstract

The invention discloses a winding skeleton of a double-column type optical fiber ring. The winding skeleton of the double-column type optical fiber ring comprises a base and a winding skeleton body, wherein the winding skeleton body is fixedly arranged on the base; the winding skeleton body comprises a blocking plate, an upper blocking plate, a lower blocking plate and four semicircular skeletons,and the four semicircular skeletons are arranged in the winding skeleton; the two semicircular skeletons are arranged between the blocking plate and the upper blocking plate, and the other two semicircular skeletons are arranged between the blocking plate and the lower blocking plate; the blocking plate is provided with a notch; a double-cavity structure is arranged in the winding skeleton and isused for containing an optical fiber ring; the double-cavity structure comprises a circular inner cavity and a circular outer cavity; the middle point after fiber splitting of the optical fiber ringis fixedly arranged at the notch of the blocking plate, and two small column type optical fiber rings of the double column type optical fiber ring are fixedly arranged in the inner cavity and the outer cavity by winding. The winding skeleton has the advantages that a safe, balanced and stable temperature environment is provided for the optical fiber ring; by arranging the novel cavity structure and the skeleton installation structure, the problem of asymmetric temperature disturbance at the upper surface and lower surface is solved.

Description

technical field [0001] The invention relates to the technical field of fiber optic gyroscope inertial instruments, in particular to a ring-wrapping frame of a double-column fiber optic ring. Background technique [0002] As an angular displacement and angular velocity sensor, the gyroscope is used to measure the attitude angle and angular velocity of the carrier. It is an important information source and core technology of the weapon system. After development in recent years, because of its own low cost, long life, light weight, With the characteristics of small size, large dynamic range and high precision, it has become an indispensable inertial device in the composition of inertial navigation system. Focusing on the overall needs of aircraft, satellites, warships, submarines and other platforms for higher precision, higher stability, and higher reliability inertial navigation systems, there is an urgent need to improve the stability and accuracy of the inertial devices use...
