Abstract
A method and apparatus for spatial modulation in the cross-process direction. A spatial light modulator includes an array (12) of individual elements. Light from a light source (14) is reflected from these individual elements onto phases of pixels (20 and 54) of an organic photoconductive drum (16) thereby determining the gray shade of that pixel. The light from the individual elements may be focused through optics (18).
