Abstract

The invention relates to a projection arrangement, comprising a projector unit (1) and a projection surface (2), whereby, in order to generate an image on the projection surface (2), the projector unit (1) illuminates the above with a light beam (5) for each image point of the image for generation. The projection surface (2) is provided with a mirror (11) and a beam divergent device (12), which, when viewed in the direction of the light beam (5), incident on the mirror, has the mirror (11) first, whereby the mirror (11) reflects all the beams of light coming from the projector unit (1), passing through the beam divergent device (12) and incident on the mirror (11), in such a way that at least one light beam (6), emerging after passing through the beam divergent device (12), is generated from a main ray (25). Main rays (25) for emergent light beams (6), emitted from adjacent areas of the projection surface (2) in a first direction, converge in an imaginary observed field (9), lying on a plane and the convergence of each emergent light beam (6), caused by the beam divergent device (12), is fixed such that the emergent light beams (6) each diverge and, in the plane, illuminate only the observed field (9).
