Detector for determining position of at least one object

A detector (110) for determining a position of at least one object (112) is proposed. The detector (110) comprises at least one sensor element (116) having a matrix (118) of optical sensors (120), wherein each optical sensor (120) has a light-sensitive area (122) and is designed to generate at least one sensor signal in response to an illumination of its respective light-sensitive area (122) by areflection light beam (182) propagating from the object (112) to the detector (110), the sensor element (116) is adapted to determine at least one reflection image (126); at least one evaluation device (128), wherein the evaluation device (128) is adapted to select at least one reflection feature of the reflection image (126), the evaluation device (128) is configured for determining at least onelongitudinal region (130) of the selected reflection feature of the reflection image (134) by evaluating a combined signal Q from the sensor signals, the evaluation device (128) is adapted to determine at least one displacemen
