Abstract

See full text

A detector (110) for determining a position of at least one object (112) is proposed. The detector (110) comprises:

    at least one transversal optical sensor (130), the transversal optical sensor (130) being adapted to determine a transversal position of at least one light beam (138) traveling from the object (112) to the detector (110), the transversal position being a position in at least one dimension perpendicular to an optical axis (116) of the detector (110), the transversal optical sensor (130) being adapted to generate at least one transversal sensor signal;at least one longitudinal optical sensor (132), wherein the longitudinal optical sensor (132) has at least one sensor region (136), wherein the longitudinal optical sensor (132) is designed to generate at least one longitudinal sensor signal in a manner dependent on an illumination of the sensor region (136) by the light beam (138), wherein the longitudinal sensor signal, given the same total power of the illumination, is dependent on a beam cross-section of the light beam (138) in the sensor region (136);at least one evaluation device (142), wherein the evaluation device (142) is designed to generate at least one item of information on a transversal position of the object (112) by evaluating the transversal sensor signal and to generate at least one item of information on a longitudinal position of the object (112) by evaluating the longitudinal sensor signal.
