Es werden Vorrichtung und Verfahren zur Dateneinspiegelung insbesondere für Windschutzscheiben bereitgestellt. Dabei wird eine holografische Mattscheibe, insbesondere eine abbildende holografische Mattscheibe, benutzt.
A device for data projection, includes a holographic element arranged as a imaging element for a windshield. An imaging device has a first imaging system and a second imaging system configured to illuminate the holographic element. The holographic element has a first volume hologram structured to be angle-selective for light under a 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 a 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.
