Abstract: The invention relates to an apparatus for the transmission of data and energy between two objects moving relative to one another about a common axis of rotation. The objects each comprise coils which are disposed opposite and are spaced apart axially with respect to the axis of rotation such that an energy transmission between the coils is possible by inductive coupling. A respective electrode carrier having a respective electrical conductor is provided coaxially to and rotationally fixed with respect to the respective coils, wherein the electrode carriers are disposed opposite and spaced apart axially and the electrical conductors are arranged such that a data transmission between the electrical conductors is possible by electrical coupling. The electrical conductors are circular or part-circular and are concentric to the axis of rotation of the relative movement. In addition, the respective coil windings and electrical conductors are arranged concentric to one another. The respective coil carriers and electrode carriers are formed in one piece and as a respective circuit board. A respective arrangement of conductive material for shielding is provided between the first coil and the electrical conductor coaxial thereto and/or between the second coil and the electrical conductor coaxial thereto. The arrangement for the electrical shielding comprises bores in the circuit board in the radial region between the coil and the electrical conductor in which bores conductive material is located. The invention furthermore relates to a laser scanner having such a transmission apparatus in accordance with the invention.

Abstract: An optoelectronic sensor is provided that has a front screen, a measuring unit, a movable deflection unit, and a contamination test unit moved along with the deflection unit for generating a received contamination test signal from contamination test light reflected at the front screen. In this respect, the contamination light unit has at least two contamination test light transmitters and/or at least two contamination test light receivers to form a plurality of contamination test channels and a control and evaluation unit is configured to detect the object by evaluating a received measurement signal of the measuring unit and to evaluate the contamination of the front screen by evaluating the plurality of received contamination test signals of the plurality of contamination test channels.
