Abstract: The invention relates to optical printers for printing onto a photosensitive substrate a succession of characters arranged in parallel lines. The optical printer according to the invention comprises a matrix of radiant energy sources capable of forming planar patterns representative of the characters to be printed; the pencils of radiant energy emerging from the matrix are transmitted toward the substrate across an afocal optical system wherein an acousto optical deviator element is positioned.

Abstract: The present invention relates to acousto-optical systems capable of deflecting a substantially monochromatic radiant energy beam. The acousto-optical system in accordance with the invention comprises an acousto-optical deflection cell surrounded by sets of prisms capable of producing anamorphosis of the transverse section of the radiant energy beam respectively ahead and beyond the deflection cell. The invention can be applied to any angular scan optical system operating with substantially monochromatic light, this at very high scanning velocities.

Abstract: The present invention relates to graphic reproduction systems capable of printing onto a photosensitive material or transferring to a substrate graphic forms such as those displayed upon the screen of a cathode-ray device. According to the present invention there is provided a graphic reproduction system wherein the writing assembly comprises : a quasi-monochromatic light source, acousto-optical modulator means transmitting the radiant energy beam issuing from said source and acousto-topical means associated with anamorphotic means of prism-type, for deflecting the modulated beam emerging from said acousto-optical modulator means. The invention allows the graphic reproduction of data displayed upon the screen of an arbitrary display device, as well as the distant graphic reproduction of arbitrary graphic forms.
