A detector ( 110 ) for optically detecting at least one object ( 112 ) is proposed. The detector ( 110 ) comprises at least one optical sensor ( 114 ). The optical sensor ( 114 ) has at least one sensor region ( 116 ). The optical sensor ( 114 ) is designed to generate at least one sensor signal in a manner dependent on an illumination of the sensor region ( 116 ). The sensor signal, given the same total power of the illumination, is dependent on a geometry of the illumination, in particular on a beam cross section of the illumination on the sensor area ( 118 ). The detector ( 110 ) furthermore has at least one evaluation device ( 122 ). The evaluation device ( 122 ) is designed to generate at least one item of geometrical information from the sensor signal, in particular at least one item of geometrical information about the illumination and/or the object ( 112 ). |
