Apparatus for generating an optical pattern from image points in an image plane, including: a control unit; a micro-mirror array; an illumination unit controllable by the control unit; a focusing unit; the control unit being configured to control one or several micro-mirror groups formed of several micro-mirrors of the multitude of micro-mirrors such that the centroid beams reflected at the micro-mirrors of one of the micro-mirror groups meet in the image plane, and such that optical path lengths of the centroid beams reflected at the micro-mirrors of the respective micro-mirror group are equal from the illumination unit up to the image plane or differ by an integer multiple of a wavelength of the light beams in order to generate an image point of the image points in such a way.
