Abstract: A holographic display system for a vehicle includes a projection unit (2), a holographic beam combiner (3), and a viewing mirror (4, 4?). The projection unit includes a light source for the emission of a luminous signal and a controllable imaging unit illuminated by the light source, with which image information can be modulated on the luminous signal. The modulated luminous signal can be directed against the holographic beam combiner. The viewing mirror (4, 4?) is provided in or on the vehicle, by which mirror light radiated from the holographic beam combiner (3, 3?) can be directed into the optical perception range of a user.

Abstract: A projection system and method are provided, the system includes a radiation source for generating electromagnetic radiation outside the visible wavelength range, an imaging unit, which can be irradiated by the radiation source, and a projection screen having a radiation-sensitive surface which, when excited by means of the above-mentioned invisible radiation, can emit fluorescent light in the visible wavelength range. The radiation-sensitive surface is formed of a material which, irrespective of the position, emits fluorescent light of different wavelengths as a function of the wavelength of the excitation radiation, and the radiation source can emit excitation radiation of different wavelengths.
