PROJEKTIONSBILDANZEIGEEINRICHTUNG MIT ZWEI MODULATIONSSTUFEN, EINSCHLIESSLICH EINER APERATUR-MODULATIONSSTUFE |
摘要 |
<p>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.</p> |
