Holographic information display

摘要

The invention relates to a method for displaying data. A first set of data and a second set of data each to be displayed are provided. A three-dimensional scenery displaying the first set of data in a first layer (3) and the second set of data in a second layer (4) is created. The first layer is separated from the second layer by a specified distance. A hologram is determined, which corresponds to a recording of the scenery via a reference beam. A plurality of controllable phase delay elements are set according to the determined hologram. The hologram is reconstructed by illuminating the plurality of phase delay elements using a coherent light source. The light of the reconstructed hologram is directed into the visual field of a driver (1) via a wind screen (2) of a vehicle.
