Abstract
An electro-optic imager, used for exposing photosensitive media imagewise, wherein an array, e.g. two or more linear arrays, of light sources are imaged onto a rotating drum, to produce images in bands. Apertures are used to shape the beam energies. The use of two or more linear arrays with interlaced imaging allows aperture shapes to be used which precisely control the region of overlapping exposures. With properly shaped apertures, scanning artifacts (e.g. aliasing) can be nearly eliminated.
