Abstract: A compact projection illumination system (6A) includes a low profile housing (20A) having an optical system (11A) for directing high intensity reflected light to an image forming display device (24A) mounted substantially horizontally in the housing (20A), a projection lens arrangement (22A) comprised of three groups of optical elements aligned along a common optical axis with a variable vertex length and wide field coverage angle, and a display control system (25A) coupled electrically to the image forming device (24A) includes a compression logic arrangement for compressing high resolution information by eliminating certain horizontal and vertical pixel image information during one frame cycle and by eliminating certain adjacent horizontal and vertical pixel image information during the next frame cycle.
