1. A detector for determining a position of at least one object, the detector comprising:
at least one transfer device with chromatic aberration;
at least one aperture element, wherein the aperture element is configured to block edge components of a 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;
at least one first optical sensor positioned in a direction of propagation of said light beam behind the aperture element, wherein the first optical sensor is configured for determining a color information of the central components of said light beam and wherein the first optical sensor is configured for determining at least one first intensity information of the central components of said light beam; and
at least one second optical sensor, wherein the second optical sensor is configured to determine at least one second intensity information of the edge components of said light beam,
wherein the detector comprises at least one evaluation device being configured for 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.
