ABSTRACT:
A linear spatial light modulator with two offset rows of pixels for slight overlap of images, and a printer system using such a spatial light modulator with dark field projection optics is disclosed. The pixels include electrostatically deflectable elements which all bend in the same direction to permit use of dark field projection. The addressing electrodes for the elements are beneath the reflecting surface and arranged perpendicular to the rows of pixels with half on each side of the rows. The printer uses a xerographic engine for conversion of modulated light into print, and an entire row is printed without any scanning.
