Abstract:
In a holographic heads-up display, a first set of data and a second set of data are provided. A three-dimensional image or scenery displaying the first set of data in a first layer and the second set of data in a second layer are 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 via a wind screen of a vehicle.
