Embodiment Construction

[0030] The technical solution of the present invention will be further described in detail below in conjunction with specific embodiments.

[0031] The invention discloses a dual-channel optical fiber rotary connector with long space life. A central channel is formed by an optical system composed of a self-focusing lens and a spherical mirror. The central channel includes two optical fiber transmission channels, which are respectively the first central channel and the second central channel. The center one channel passes through the beam expander and coupling part of the optical system and then enters the one channel receiver to realize the signal coupling and alignment of the center one channel. The rotational symmetry of the optical system ensures the continuous transmission of the center one channel. For the center two channels, Since the two-channel incident light collimating component and the two-channel receiver are coaxial, optical signals can be transmitted in parallel ...

Abstract

The invention provides a space long-service-life dual-channel optical fiber rotary connector. The problems that an existing dual-channel optical fiber rotary connector is short in service life, largein loss, prone to failure and complex in structure are solved. The optical fiber rotary connector comprises a stator shell, a rotor sleeve, a first center channel unit, a second center channel unit, afront end cover and a rear end cover. The stator shell is of a sleeve structure, the rotor sleeve is installed on the front side of a cavity of the stator shell through a bearing assembly, the frontend cover is arranged at the front end of the rotor sleeve, and the rear end cover is arranged on the rear side of the cavity of the stator shell. The first central channel unit comprises a first rotor tail fiber, a first channel incident light collimation assembly, an optical system beam expanding assembly, an optical system coupling assembly, a channel receiver and a first stator tail fiber which are coaxially arranged in sequence; the second central channel unit comprises a first rotor tail fiber, a second channel incident light collimation assembly, a second channel receiver and a second stator tail fiber.

Description

technical field [0001] The invention belongs to the field of optical fiber communication, in particular to the field of large-capacity, high-speed signal long-time transmission in space, and in particular to a space long-life dual-channel optical fiber rotary connector, which is mainly used in a space environment with two-way channel optical fiber between relative rotating devices. The occasion of signal rotation coupling transmission. Background technique [0002] Optical fiber rotary connector is a device that uses optical fiber as a transmission medium to transmit signals between a rotating platform and another stationary platform. With the rapid development of signal transmission, fiber optic rotary connectors are widely used in civil and military fields. [0003] Civilian fields are mostly used in medical equipment, industrial control, energy development, etc. In medical equipment, it is generally used in CT scanning systems and OCT coherent imaging systems, and the o...
