Abstract
An apparatus for printing images including illumination optics (75) that provides uniform area light is disclosed. A mirror (440) receives the uniform area light and redirects the light. A first reflective LCD modulator (90) modulates the redirected light on a site by site basis and reflects the first modulated light to a media plane. A motor (441) moves the mirror on a line parallel to the illumination optics. The mirror redirects the light to a second reflective LCD modulator (95). The second reflective LCD modulator modulates the redirected light on a site by site basis and reflects the second modulated light to the media plane.
