Abstract

An image is produced in an image plane using a row of semiconductor laser emitters which provide a corresponding row of outlet spots as light sources. An optical projection system receives radiation from the outlet spots and the radiation on the image plane as one or more rows of images by virtue of the illumination of individual, adjacently located imaging spots. The optical projection system associates at least one outlet spot with each of the imaging spots, and simultaneously forms the image of the outlet spots of all of the semiconductor laser emitters of the row of light sources at the imaging spots associated therewith.
