Abstract (en)
[origin: WO03056389A1] The invention relates to a projection system comprising a projection device which is used to produce a projection by emitting projection radiation, and a diaphragm device which is arranged in the beam path of the projection radiation in such a way that part of the projection is blocked out, thus causing a continuous reduction of the intensity of the projection radiation in the blocked-out part of the projection.
