Abstract

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.
