Abstract
Apparatus and techniques for enhancing characteristics of electronic projection systems are detailed. Included among the techniques are both superimposition of sub-images and tiling of superimposed images, the combination of which can be advantageous in improving resolution of projected images. Pre-modulators and polarizing beam splitters also may be used as parts of the innovative systems.
