Abstract

A rotating optical coupler for coupling optical signals from a first set of rotating optical conductors to a second set of stationary optical conductors includes a plurality of annular lenses, each of which is optically associated with one of the optical conductors of the first set. The lenses are nested one inside another to form a lens assembly oriented in a plane perpendicular to optical axes of the lenses. A rotating holder supports each of the conductors of the first set in parallel orientation with respect to an optical axis of a central one of the annular lenses with each conductor being positioned at a different radial distance from the optical axis of the central lens. Ends of the conductors are positioned to direct light rays at a corresponding one of the annular lenses. A second stationary holder supports ends of each of the conductors of the second set at a focal point of a respective one of the annular lenses. The second holder is coupled to the lens assembly for maintaini
