Abstract
Used are an imaging apparatus for a device for data projection and an optical component and a corresponding device for data projection. The imaging apparatus here comprises a plurality of light-emitting elements, arranged in a first direction, and a deflection apparatus for deflecting light beams in a second direction. The optical component can comprise a windshield which is provided with holograms.
Claims20
An imaging apparatus, comprising:
- a plurality of light-emitting elements arranged in a first direction along a line for generating a plurality of modulatable light beams;
- wherein the plurality of light-emitting elements comprises a plurality of optical elements, which are arranged in the first direction, and a laser projector apparatus for scanning the optical elements in the first direction;
- a deflection apparatus for adjustably deflecting the plurality of modulatable light beams in a second direction, wherein the second direction differs from the first direction;
- and
- wherein the deflection apparatus comprises a rotating element and the optical elements are arranged on the rotating element.
