摘要： A device fro projection onto a dome has several projectors (50, 51, 54, 56) for representing images on an at least partly spherical projection surface (52), each projector (50, 51, 54, 56) being arranged so that it illuminates one or more partial surfaces (56, 58) on the projection surface (52) with partial images. A light source (12) and a deflection device (40) are provided for one or more of the projectors (51, 54, 56), by means of which a beam of light (10) emitted from the light source (12) to represent the image can be guided over the part to be illuminated. The deflection device (40) for the one or more projectors (51, 54, 56) is designed as a grid device with which the beam of light can be guided in several lines with several picture elements over the partial surface (56, 58) to be illuminated, and the light source (12) is connected to an intensity control (64), which allows individual pixels to be illuminated with suitable luminance to represent the partial image (56, 58).
