Claim 11:
12. A method for determining a position of at least one object, wherein a detector according to claim 1 is used, the method comprising the following steps:
illuminating at least one first optical sensor positioned in a direction of propagation of a light beam propagating from the object to the detector and having passed at least one transfer device with chromatic aberration behind at least one aperture element, wherein the aperture element is configured to block edge components of the light beam propagating from the object to the detector and having passed the transfer device, wherein the aperture element is configured to let pass central components of said light beam;
determining a color information of the central components of said light beam with the first optical sensor and determining at least one first intensity information of the central components of said light beam by using the first optical sensor; and
determining at least one second intensity information of the edge components of said light beam by using at least one second optical sensor;
wherein the method further comprises determining at least one longitudinal coordinate zDPR of the object by evaluating a combined signal Q from the first intensity information of the central components and the second intensity information of the edge components by using at least one evaluation device.
