Abstract
A device for generating a partial annular or an annular picture on a portion of a spherical projection surface by an annular mirror by which a light bundle generating this picture can be deflected onto the projection surface has a light source by which substantially parallel light bundles can be generated, a control unit for controlling the intensity of the light bundle, and a raster scanning device which is arranged in the light path between the annular mirror and the light source and which can raster scan the light bundle in two dimensions for the sequential illumination of picture points of the annular picture or partial annular picture.
