Abstract
An apparatus and method of printing two-dimensional swaths of area onto a photosensitive media uses at least one reflective liquid crystal spatial light modulator. In the apparatus and method, illumination optics receive light from a light source and image the light at a polarization beamsplitter element. The polarization beamsplitter element images one polarization state of light at the spatial light modulator to create an essentially telecentric illumination at the spatial light modulator.
