Abstract

In an image-reproducing system in which a number of beams scan over a record medium together and contribute to the formation of half-tone dots, an anamorphic system is included in the beam path to match the beam cross-section to the shape of mask apertures in the light paths and to compress the length of the line of beams, transverse to their direction.
