Abstract
An apparatus and method of printing two-dimensional swaths of area onto a photosensitive media (80) uses at least one reflective liquid crystal spatial light modulator (60). In the apparatus and method, illumination optics receive light from a light source (20) and image the light at a polarization beam sputter element (50). The polarization beam splitter element (50) images one polarization state of light at the spatial light modulator to create a substantially collimated illumination at the spatial light modulator.
