    摘要: A device for data projection, comprising a holographic element to be arranged by a windshield. An imaging device comprising a first imaging system is arranged at a first angle with respect to the holographic element and configured to illuminate the holographic element at a first illumination angle with first illumination light modulated with first image data. A second imaging system is arranged at a second angle with respect to the holographic element and configured to illuminate the holographic element at a second illumination angle different from the first illumination angle with second illumination light modulated with second image data such that on the holographic element the first illumination light overlaps with the second illumination light. The holographic element comprises a first volume hologram structured to be angle-selective for light under the first illumination angle and to generate a first two-dimensional virtual image at a first fixed distance from the holographic element corresponding to the first image data, and a second volume hologram structured to be angle-selective for light under the second illumination angle and to generate a second two-dimensional virtual image at a second fixed distance from the holographic element different from the first distance corresponding to the second image data, such that the first and second images are viewable separately and simultaneously by a person.

    摘要: 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.

    摘要: 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 (10), arranged in a first direction, and a deflection apparatus (11) for deflecting light beams in a second direction. The optical component can comprise a windshield which is provided with holograms.
