Abstract

Disclosed herein is a projector for illuminating at least one object with at least one illumination pattern. The projector includes at least one array of vertical-cavity surface-emitting lasers (VCSELs). Each of the VCSELs is configured for generating at least one light beam. The projector includes at least one optical system configured for generating a characteristic beam profile for each of the light beams generated by the VCSELs of the array. The beam profile of neighboring VCSELs of the array differs in lateral and/or axial direction such that light beams of the VCSELs of the array are assignable to the corresponding VCSEL in three-dimensional space.
