Abstract: An optoelectronic sensor for detecting objects in a monitored zone is provided, wherein the sensor comprises a laser scanner having a deflection unit rotatable about an axis of rotation for scanning the monitored zone with at least one scanning beam; a first distance measurement unit for determining 3D measurement points of the respective objects impacted by the scanning beam using a time-of-flight method; a panorama camera having a panorama optics and having an image sensor with a plurality of light reception elements for detecting picture elements; and a control and evaluation unit that is configured to fuse the 3D measurement points and the picture elements. In this respect, the optical axis of the panorama camera and the rotation axis coincide.

Abstract: An optoelectronic sensor for detecting objects in a monitored zone is provided that has at least one light transmitter for transmitting a plurality of mutually separated light beams, a transmission optics for the transmitted light beams, at least one light receiver for generating a respective reception signal from light beams remitted by objects, a reception optics for the remitted light beams, and a control and evaluation unit for obtaining information on the objects from the reception signals, wherein the transmission optics and/or the reception optics has/have a first optical system. In this respect, the transmission optics and/or the reception optics has/have a second optical system for correcting aberrations comprising a plurality of optical correction elements that are each associated with a light beam and the second optical system is arranged between a beam separation plane.

Abstract: A heatable cover for an optical sensor comprises a transparent cover element, a transparent and electrically conductive coating that is arranged at the cover element, and at least two electrodes that are spaced apart from one another and that are each in contact with the conductive coating. A respective distance between a respective two of the electrodes is defined along a respective distance line across the coating. Each of the at least two electrodes further has at least one contacting position at which the respective electrode is connected to a voltage source. The contacting positions of a respective two electrodes are spaced apart from one another in a direction that extends at a right angle to the distance line.
