An optoelectronic sensor for the detection of objects in a monitored zone is provided that has a light transmitter for transmitting a light beam, a light receiver for generating a received signal from the light beam remitted by the objects in the monitored zone, a control and evaluation unit for the detection of information on the objects with reference to the received signal, a base unit, a scanning unit movable with respect to the base unit for the periodic scanning of the monitored zone, and a drive having a hollow shaft for moving the scanning unit, wherein the scanning unit comprises a first data transmission unit and the base unit comprises a second data transmission unit to exchange data wirelessly between the base unit and the scanning unit through the hollow shaft, The first data transmission unit and the second data transmission unit are configured as microwave units for the data exchange by means of microwave signals.

Optoelectronic sensor and method for detecting objects

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.

Apparatus for transmitting data and energy between two objects moving relative to one another

An optoelectronic sensor () for the detection and distance determination of objects in a monitored area () transmits a transmission light beam (), generates a reception signal from remitted transmission light (), and determines an object distance from a light time of flight. A reception path between light receiver () and evaluation unit () is divided into a first and a second partial reception path () at a splitter element () comprising filtering properties to pass higher frequency parts of the reception signal on to the first partial reception path () and lower frequency parts on to the second partial reception path (). An object's distance is determined from the first and an opacity from the second partial reception signal.
