Abstract

This invention relates to electro-optic line printers and, more particularly to dual region TIR (total internal reflection) modulators. An electro-optical modulator is disclosed wherein the driving electrodes are implemented in two offset, but connected, sections to effectively double the output resolution of the modulator. Longitudinally displaced, laterally staggered electrode arrays are used to produce the laterally staggered fringe field patterns. Since the impinging light beam will defocus while being deflected, means are provided to focus the beam into first and second interaction regions being addressed.
