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 ...
