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 method for illuminating the surface of an object by using a source beam is provided. The source beam is partitioned into as many illumination sub-beams as there are surface elements to be illuminated, and their aperture is modulated as a function of the predetermined luminous intensity to be assigned to the surface element. Each surface element is illuminated with the aid of one of said illumination sub-beams. Used for illuminating the imagers of projection devices, this method makes it possible to add a second modulation stage allowing the display contrast of the images to be improved.
