Abstract (en)
[origin: WO9424615A1] A holographic display device particularly useful for displaying information in the form of words is made up of an array of identical holograms each containing all the patterns necessary to form the whole of the information to be displayed. Each hologram is formed either using a master hologram or directly by creating multiplexed patterns from a number of different parts of the information to be displayed. Such a display creates the impression of an image which moves with the viewer which is advantageous for warning signs or road signs.
