ABSTRACT:
A projector includes an array of micromirror light modulators and a projector light source for generating an illumination light beam along an optical path. An elongated rectilinear illumination aperture is defined at a first location along the optical path, with one or more elongated regions having a long dimension parallel to the axis. An elongated rectilinear pupil aperture is defined at an output pupil with one or more elongate pupil regions having a long dimension parallel to the axis.
