Abstract:
1. A projection system for projecting an image comprising a matrix of pixels having modulated luminance, the projection system comprising: a first imager 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 positioned and configured to receive the first output matrix of modulated pixels of light 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 of the image; and a relay lens system configured to focus the modulated light output from the first imager on a pixel-by-pixel basis onto the corresponding pixels of the second imager, the relay lens system including a single-gauss lens set and a mirror positioned at the system stop for the lens set to reflect the image back through the lens set.
