Abstract
An optical rotating data transmission device for polarization-maintaining transmission of linearly polarized light includes at least one first collimator for coupling on first light-waveguides, and also a second collimator for coupling on second light-waveguides, the second collimator being supported to be rotatable relative to the first collimator about a rotation axis. At least two λ/4 plates for converting linear polarization to circular polarization and vice-versa are provided in between a plate for attaching optical fibers and a micro lens system.
