<p>Method of illuminating the surface of an object using a source beam in which: said source beam is divided into as many illumination sub-beams as there are surface elements to be illuminated, the aperture of which is modulated according to the predetermined light intensity to be assigned to said surface element; and each surface element is illuminated by one of said illumination sub-beams. Used to illuminate the imagers of projection devices, this method allows a second modulation stage to be added, thereby improving the display contrast of the images. ® KIPO & WIPO 2009</p> |
