<p>An apparatus and technique for enhancing characteristics of electronic projection systems. Techniques may include both superimposition of sub-images and tiling of superimposed images, the combination of which can be advantageous in improving resolution of projected images. The apparatus may include first and second SLA sets (1, 2) for forming the sub-images and a pyramid prism (10) for enacting the tiling of images. Pre-modulators and polarizing beam splitters (6, 7, 8) also may be used as parts of the system.</p>
