Abstract

The invention discloses a double-channel fiber optic rotary connector. The connector comprises a rotating mechanism, a static mechanism, a bi-cylindrical de-rotating prism and a gear component, wherein the rotating mechanism and the static mechanism are oppositely arranged at the two ends of the bi-cylindrical de-rotating prism; two collimation optic fibers are arranged in both the rotating mechanism and the static mechanism and one optic fiber in the two collimation optic fibers is arranged in the center of the rotating mechanism or the static mechanism; a connecting line of the centers of the rotating mechanism and the static mechanism is overlapped with a central axis of the bi-cylindrical de-rotating prism; focal planes of symmetric cylindrical surfaces on two sides of the bi-cylindrical de-rotating prism are both positioned on central tangent planes of the rotating prism; the rotating mechanism is connected with the bi-cylindrical de-rotating prism through the gear component in a rotating manner. By using the bi-cylindrical de-rotating prism, de-rotating of a light beam can be realized, the light path is simple, a light signal is easy to couple, and the coupling loss is reduced while double-channel rotary transmission is realized.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a dual-channel optical fiber rotary connector. Background technique [0002] Optical fiber rotary connector is the core device to realize data transmission between rotating platform and stationary platform, and is widely used in radar antenna, navigation and other systems. Common optical fiber rotary connectors are divided into single-channel optical fiber rotary connectors and multi-channel optical fiber rotary connectors. [0003] The existing single-channel optical rotary connector has the characteristics of simple structure, small size, and direct optical coupling, which make it widely used, but its low reliability and small transmission capacity limit some of its applications. Modern information control and processing systems put forward higher requirements for signal transmission capacity and bandwidth. At the same time, in radar, navigation, etc., it i...
