Abstract
The invention refers to an apparatus for generating two-dimensional and/or three-dimensional objects. The apparatus comprises at least one spatial light modulator device for modulating incident light and an optical system. The optical system is designed and arranged such that a segmentation of wave fields is provided in a plane, where the plane in which the segmentation of the wave fields is provided differs with a plane that comprises object points. Adjacent segmented wave fields do have a mutual overlap. The apparatus also comprises a scanning device which couples light waves into a beam expanding waveguide with outcoupling gratings.
