Abstract
An imaging system for imaging a plurality of macropixels onto a media and a method for generating a linear array of macropixels to be imaged onto a media utilizing a two dimensional spatial light modulator having a plurality of micropixels grouped together to form a plurality of linear arrays of macropixels is provided. The imaging system includes a light source for generating a beam of light; a projection lens assembly for focusing the beam of light; a deflector illuminated by the light beam output from the projection lens assembly, the deflector able to deflect the light beam in the vertical (Y-axis) direction; an anamorphic lens assembly illuminated with the light beam output from the deflector; a two dimensional spatial light modular (SLM) including a plurality of micropixels, the plurality of micropixels grouped together to form a plurality of linear arrays of the micropixels, and an imaging lens assembly coupled to the output of the spatial light modulator. The spatial light modulator controls the passage of light through each of the macropixels, the linear arrays being illuminated one at a time in sequential order. The imaging lens assembly images onto the media, a line spot…
