Abstract
The invention discloses a multichannel multispectral optical fiber rotary connector which is composed of an outer casing component, a fixed end collimator component, a rotary end collimator component and a ring-core component. A reflecting surface of a reflecting mirror (10) is in parallel to a central shaft, an include angle of one reflecting surface of a reflecting prism (9) and the reflecting surface of a reflecting mirror (10) and an include angle of another reflecting surface of a reflecting prism (9) and the reflecting surface of the reflecting mirror (10) are equal, and the ratio of the distance between an intersecting line of the two reflecting surfaces of the reflecting prism (9) and the central axis to the distance between the reflecting surface of a reflecting lens (8) to the central axis is a value which is the square of a tangent value of the included angle of the reflecting surface. By utilizing the multichannel multispectral optical fiber rotary connector, incident light of an optical fiber signal is ejected in an opposite image by a lens group, and the lens group rotates at a speed which is half of that of a rotary end so as to realize transmission of the optical fiber signal in the rotation. In an entire optical path, the optical path can be changed only by reflection, and the relatively high performance can be obtained in a relatively wide frequency band. Refraction does not exist in the entire optical path, and the lens can not be burnt when a high-power signal is transmitted so that the user security and the service life of the optical fiber rotary connector are effectively guaranteed.
