Abstract
A detector () for determining a position of at least one object (), the detector () comprising: at least one transfer device () for imaging the object () into an image plane (), the transfer device () having a focal plane (), at least one longitudinal optical sensor (), wherein the longitudinal optical sensor () has at least one sensor region (), wherein the longitudinal optical sensor () is at least partially transparent, wherein the longitudinal optical sensor () is designed to generate at least one longitudinal sensor signal in a manner dependent on an illumination of sensor region () by at least one light beam propagating from the object to the detector (), wherein the longitudinal sensor signal, given the same total power of the illumination, is dependent on a beam cross-section of the light beam in the sensor region (); and at least one evaluation device (), wherein the evaluation device () is designed to generate at least one item of information on a longitudinal position of the object () by evaluating the longitudinal sensor signal. Herein the at least one longitudinal optical sensor () comprises a focal longitudinal optical sensor (), wherein the focal longitudinal optical sensor () at least substantially is arranged in the focal plane ().
