A double-column optical fiber ring around the ring skeleton

Abstract

The invention discloses a double-column type optical fiber ring surrounding framework. The double-column optical fiber loop surrounding framework comprises a base and a surrounding framework, and the surrounding framework is fixedly installed on the base; the surrounding framework comprises a baffle plate and an upper baffle Plate, lower baffle and four semicircular skeletons arranged therein; two semicircular skeletons are arranged between the baffle and the upper baffle, and the other two semicircular skeletons are arranged between the baffle and the lower baffle There is a gap on the baffle; a double-cavity structure for placing the optical fiber ring is arranged inside the ring skeleton, and the double-cavity structure includes a circular inner cavity and an outer cavity; the middle cavity after the optical fiber ring is split The point is fixed on the gap on the baffle plate, and the optical fiber is wound so that the two small cylindrical optical fiber rings of the double cylindrical optical fiber ring are respectively fixed in the inner cavity and the outer cavity. The invention provides a safe, balanced and stable temperature environment for the optical fiber ring, and the novel cavity structure and installation frame structure can solve the problem of asymmetrical temperature disturbance on the upper and lower sides.

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...
