A holographic optical element comprising at least two sets of regions, the regions of each set being different from the regions of the other set(s) and being interleaved or overlapping with the regions of the other set(s) and being constructed such that light incident on each set of regions is directed to a respective one of a plurality of viewing zones. The holographic optical element is typically incorporated in a display device such as a stereoscopic display device.

Un élément optique holographique comprend au moins deux ensembles de régions, les régions de chaque ensemble étant différentes des régions de l'autre (des autres) ensemble(s) et étant imbriquées dans les régions de l'autre (des autres) ensemble(s) ou les chevauchant, cet élément étant conçu de sorte que la lumière incidente sur chaque ensemble de régions soit dirigée vers une zone de visualisation respective d'une pluralité de telles zones. L'élement optique holographique est généralement incorporé dans un dispositif d'affichage, tel qu'un dispositif d'affichage stéréoscopique.
