Abstract
Micro-electromechanical display device ('MDD')-based multimedia projectors () of this invention employ an arc lamp (), a color modulator (), and anamorphic illumination systems () for optimally illuminating a MDD () to improve projected image brightness. MDDs employ off-axis illumination wherein incident and reflected light bundles are angularly separated about a hinge axis () and the MDD is illuminated by the anamorphic illumination systems of this invention having a slow f/# parallel to the hinge axis and a faster f/# perpendicular to the hinge axis. The resulting anamorphic light bundles () illuminate and reflect more light into and off the MDD and through a fast f/# projection lens.
