摘要： A detector for object authentication includes first and second illumination sources. The first illumination source projects an illumination pattern including a plurality of illumination features onto a surface of an object. The second illumination source projects an illuminating light beam onto the object. The detector also includes an image capture device for determining a first image including a plurality of reflection features generated by the surface of the object in response to the illumination pattern and for determining a second image including two dimensional information associated with the surface of the object generated in response to the illuminating light beam. The detector also includes an evaluation device for evaluating the first image and the second image, identifying a geometrical feature of the object, determining a material property of the object, and comparing the two dimensional information to data stored in a database for authentication of the object.

摘要： A detector (110) for determining a position of at least one object (112) is proposed. The detector (110) comprises: —at least two optical sensors (118, 120, 176), each optical sensor (118, 120, 176) having a light-sensitive area (122, 124), wherein each light-sensitive area (122, 124) has a geometrical center (182, 184), wherein the geometrical centers (182, 184) of the optical sensors (118, 120, 176) are spaced apart from an optical axis (126) of the detector (110) by different spatial offsets, wherein each optical sensor (118, 120, 176) is configured to generate a sensor signal in response to an illumination of its respective light-sensitive area (122, 124) by a light beam (116) propagating from the object (112) to the detector (110); and—at least one evaluation device (132) being configured for determining at least one longitudinal coordinate z of the object (112) by combining the at least two sensor signals.
