Abstract: A camera for detecting an object in a detection zone is provided that has an image sensor having a plurality of light reception elements for the generation of image data from received light from the detection zone), a reception optics having a focus adjustment unit for setting a focal position, with an angle of incidence of the received light on the image sensor changing on a change of the focal position, and a control and evaluation unit that is configured to set the focal position for a sharp recording of image data of the object, A sensitivity change of the capturing of the image data caused by the respective angle of incidence of the received light is compensated.

Abstract: The present invention relates to an optical sensor for the detection of at least one height profile of an object surface in accordance with the principle of light sectioning method. The optical sensor comprises a light transmitter which is configured to project at least one light line onto the object surface, a receiving unit comprising a light receiver having an array of receiving elements and a receiving optics arranged upstream of the light receiver for generating an image of the at least one projected light onto the light receiver, and an evaluation unit connected to the light receiver and configured for determining the height profile from an image of the at least one projected light line recorded by the light receiver. The receiving unit further comprises a tuneable aperture associated with the receiving optics and configured for varying the size and/or the shape of the aperture of the receiving optics, wherein the evaluation unit is configured for controlling the tuneable aperture in dependence from at least one image parameter of the image of the at least one projected light line.

Abstract: A camera for recording 3D image data using a light sectioning process is provided that has an illumination unit to project a light pattern in a focal plane, an image sensor having a plurality of light reception elements in an image plane, a reception optics upstream of the image sensor and having an objective plane, and a control and evaluation unit that is configured to generate the 3D image data by evaluating the light pattern in a recording of the image sensor, wherein the image plane is tilted with respect to the focal plane. In this respect, the reception optics has at least one metaelement here that compensates an oblique light incidence on the light reception elements.

CPC classification number: G06K7/10722 , G06K7/1413
Abstract: An optoelectronic sensor is provided that has an image sensor for the detection of image data in its field of view and an aiming device having a light source that is arranged laterally offset from the image sensor and that is configured to generate alignment light and thus a light pattern in the field of view to make the position and/or extent of the field of view in space visible. In this respect, the aiming device has at least one optical metaelement having a metasurface and/or a metamaterial that is arranged and configured such that the optical axes of the image sensor and the aiming device are coaxially superposed.
