ABSTRACT:
A device for transmitting modulated optical signals between a first unit and a second unit, in which the first unit is supported to be rotatable relative to the second unit, comprises a light guide along a circular track on the first unit, a first light coupler for coupling light into or out of the light guide, and a second light coupler disposed on the second unit and movable relative to the light guide, for coupling light into or out of the light guide. A coupling of light into the light guide is effected by means of a beam splitters and a light deflecting means.
