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.
