A projection system is provided with improved contrast and reduced artifacts using a larger lamp to maintain good lamp life. The projection system uses two imagers, the first being larger to accommodate a large lamp, sized to the first imager and the second being smaller. The first imager has a matrix of pixels for modulating light on a pixel-by-pixel basis to form a first modulated matrix of light. The second imager has a matrix of pixels corresponding to the pixels of the first imager for modulating the first modulated matrix of light on a pixel-by-pixel basis to form a second modulated matrix of light. The second imager having a size smaller than the size of the first imager. A relay lens set provides a magnification of less than 1.0 to relay each pixel of light in the first modulated matrix of light onto a corresponding pixel of the second imager. ® KIPO & WIPO 2007 |
