The digital projector comprises an array of light modulators displaying the image information. An optical system is arranged downstream of the light modulators and is made up of mirrors and/or prisms, with the mirrors and/or prisms being arranged such that the light beams coming from the individual light modulators are combined in front of a projection lens. For simplification of the optical system the light modulators are arranged in checkerboard formation.

Digital projector with an optical system for compensating the optical

The invention relates to a flash device, preferably for transferring a dye matrix which by means of a high-energy light flash is transferred from a radiation-absorbing carrier film by interleaving a mask onto a receiver element. This requires substantially perpendicular irradiation of the transfer plane with a high-energy radiation and a high uniformity of irradiance distribution of the light flash. To achieve this, one or two linearly extending plasma discharge tubes are provided which to concentrate radiation are enclosed by two separate aspheric-cylindrical reflectors, the concentrated radiation being directed through a lamellar louver element arranged downstream of the reflector and impinging on the predetermined transfer plane in a substantially parallel and perpendicular manner.
