A detector (110) for an optical detection of at least one object (112) is proposed. The detector (110) comprises: - at least one longitudinal optical sensor (114), wherein the longitudinal optical sensor (114) has at least one sensor region (130), wherein the longitudinal optical sensor (114) is designed to generate at least one longitudinal sensor signal in a manner dependent on an illumination of the sensor region (130) by the light beam(132), wherein the longitudinal sensor signal, given the same total power of the illumination, is dependent on a beam cross-section of the light beam (132) in the sensor region(130), wherein the longitudinal optical sensor comprises at least one photodiode (134), the photodiode (134) having at least two electrodes (166, 174), wherein at least one photoactive layer (180) comprising at least one electron donor material and at least one electron acceptor material is embedded between the electrodes(166, 174); and - at least one evaluation device (150), wherein the evaluation device (150) is designed to generate at least one item of information on a longitudinal position of the object (112) by evaluating the longitudinal sensor signal. Thereby, a simple and, still, efficient detector for an accurate determining of a position of at least one object in space is provided which exhibits the FiP effect with an improved signal-to-noise ratio and may, concurrently,be produced in a time-and energy-saving manner. |
