Abstract

The invention relates to a method for the spatial representation of a scene for at least one observer (3), according to which a plurality of views of a scene are imaged onto a holographic projection screen (2), each view being imaged onto the holographic projection screen (2) in an imaging direction which is different from the imaging directions for the other views. Light hitting the holographic projection screen (2) is diffracted according to the imaging directions such that an observer (3) perceives different quantities of views respectively with the left eye and the right eye and a spatial impression is created. The invention also relates to a corresponding arrangement characterised in that, for each view, the diffracted light is radiated in a plurality of first-order diffraction corridors in respectively median radiation directions according to the imaging direction, diffraction images in the form of diffraction fringes extending essentially parallel to each other are produced in a plane parallel to the projection screen (2), at a pre-defined observation distance, and between two diffraction fringes associated with a view, a diffraction fringe of each of the other views is produced.
