ABSTRACT:
An optical rotating data transmission device comprises a first collimator arrangement for coupling-on first optical waveguides, a second collimator arrangement for coupling-on second optical waveguides, which is supported to be rotatable relative to the first collimator arrangement about a rotation axis, and a derotating element such as a Dove prism in a light path between the collimator arrangements. At least one collimator arrangement comprises a deflecting element which deflects light entering the device from optical waveguides positioned at an angle to the direction of the rotation axis to travel along the direction of the rotation axis, or deflects light traveling along the direction of the rotation axis to exit the device at an angle to the rotation axis towards optical waveguides.
