ABSTRACT:
This specification discloses a method and apparatus for imaging light on a medium to form a plurality of information elements which in turn form a particular character or other image information. A plurality of light beams are formed and are modulated by information signals and then the light beams are deflected by scanning means to scan a medium, the beams being modulated in such a manner that the same modulation is applied to a predetermined number of the light beams in accordance with a desired size of the information elements formed on the medium, and wherein the size of the information elements, defined by adjacent rows of identical light spots, is changed by varying the number of light beams receiving the same modulation.
