Abstract:
A video projection system for projecting more than one picture comprising:a light source for generating at least one light bundle;means for intensity modulation and means for spatial light bundle modulation, said means being controlled by a video signal; andat least one projection surface for showing a determined quantity or quantities of individual pictures, said elements being arranged in the direction of light of a beam path;said video projection system further comprising a quantity or quantities of projectors which correspond(s) to the quantity or quantities of individual pictures;each said projector having means for spatial light bundle modulation, wherein these means are optically connected with the light source;means for dividing the light bundle into a quantity or quantities of partial light bundles which correspond(s) to the quantity of projectors being arranged following said light source, considered in the direction of the beam path;each of said partial light bundles having a partial beam path, followed in each partial beam path by means for intensity modulation;said means for intensity modulation and said means for spatial light bundle modulation, which are arranged in one of the partial beam paths, being controlled by signals of a video source.
