Abstract

For the transmission of a plurality of light channels between two parts which rotate relative to each other, an optical transmission element is arranged with its optical axis OA coaxial to the axis of rotation and light transmitters in different radial regions. By convex lenses or mirrors the bundles of rays coming from the light transmitters are parallelized and impinge on the optical transmission element which individually focuses the bundles of rays. In order to obtain an imaging scale of 1:1 a synchronously rotating rhomboid prism or a parabolic mirror can be used. In addition, HF channels can be transmitted.
