Abstract: An optical rotary joint for optical signal transmission is described, said optical rotary joint having at least two units that are respectively rotatably mounted about an axis of rotation, the axes of rotation of which, at least in sections, have a lateral distance from one another. The invention is distinguished by a rotary transformer that is embodied in the form of an endless loop respectively resting in a circumferential manner on both units along a contact region and positively coupling the at least two units with one another in a rotationally movable manner. Attached to both units is respectively one optical unit for conjoint rotation, said optical unit comprising at least one optical signal line, a beam splitter and/or beam coupler, which is optically coupled to the at least one optical signal line, and at least two optical partial signal lines, said optical unit being optically coupled to the at least one optical signal line via the beam splitter and/or beam coupler.

Abstract: The invention is characterized by optical deflector units comprising at least two optical reflectors, which are in case rigidly connected to one another indirectly or directly via a retaining element, and in that a first of the two retaining elements is indirectly or directly in engagement with the first coupling component via a mechanical gear unit providing a rotatable operative connection.
