Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with specific embodiments.
[0020] Such as figure 1 As shown, the basic structure of a dual-channel optical fiber rotary connector of the present invention includes a rotating shaft, a central channel, and a paraxial channel. The central channel is composed of a central incident collimator 4 and a central receiving collimator 6; the paraxial channel is composed of a paraxial incident collimator 5, a convex lens 15, a concave lens 13 and a paraxial receiver 10. The central incident collimator 4, the central receiving collimator 6 and the paraxial receiver 10 are all arranged on the rotation axis; the paraxial incident collimator 5 is eccentrically arranged with respect to the rotation axis, and The rotation axis is parallel; a center hole is punched in the center of the convex lens 15 to fix the center receiving collimator 6; the optical axes of the convex lens 15 and the concave lens 13 are coa...
