Detector for optically determining a position of at least one object

A method for optically determining a position of at least one object, the method comprising:

• determining a position of at least one light beam with at least one optical sensor
• Wherein, during said determining, the optical sensor determines a position of at least one light beam traveling from the object to the detector, wherein the optical sensor has at least a first electrode and a second electrode, wherein at least one photovoltaic material is embedded in between the first electrode and the second electrode, wherein the photovoltaic material is adapted to generate electric charges in response to an illumination of the photovoltaic material with light, wherein the first electrode or the second electrode is a split electrode having at least three partial electrodes, wherein each partial electrode is adapted to generate at least one sensor signal, wherein the sensor signal is dependent on a beam cross-section of the light beam in a sensor region of the optical sensor;
• and
• generating at least one item of information,
• wherein, during said generating, at least one evaluation device generates at least one item of information on a transversal position of the object, the transversal position being a position in at least one plane perpendicular an optical axis of the detector, by evaluating the sensor signal of pairs of the partial electrodes, and wherein the evaluation device further generates at least one item of information on a longitudinal position of the object by evaluating a sum of the sensor signals of all partial electrodes.
