Abstract
An optical rotary joint includes a rotating input lens assembly which emits a ray set from a focal point to illuminate a cylindrical reflector. Rays reflected from the cylindrical reflector pass through another focal point and are reflected from the cylindrical reflector to pass through still another focal point. This reflection and focusing continues until the ray paths are incident to a window in the cylindrical reflector and exit. Exiting rays are focused by a lens arrangement which focuses the rays to an output optical fiber.
