摘要： A two-stage light projection system is provided for projecting an image comprising a matrix of light pixels having modulated luminance. A first imager is configured to modulate a light band on a pixel-by-pixel basis proportional to gray scale values provided for each pixel of the image to provide a first output matrix. A second imager is positioned and configured to receive the first output matrix and modulate the individual modulated pixels of light from the first imager on a pixel-by-pixel basis proportional to a second gray scale value provided for each pixel. A relay lens system having a single-gauss lens set and a mirror positioned at the system stop focuses the modulated light output from the first imager on a pixel-by-pixel basis onto the corresponding pixels of the second imager.

摘要： 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.

摘要： An apparatus for adding red light to a polarized light system includes a first light source and a second light source. A polarizing beam splitter combines S-polarized-light from the first light source and P-polarized light from the second light source. A first multi-layer filter means rotates the polarization state of the green light from the first light source to the P-polarization state. A second multi-layer filter means rotates the first light source red light to the P-polarization state and rotates the second light source red light to the S-polarization state. Finally, a reflective cleanup polarizer reflects the P-polarized-light back to the respective first and second light source and passes the S-polarized-light.
