Title (EN) CUSTOMIZED REFLECTION PROFILES FOR RETRO-REFLECTIVE DISPLAY SYSTEM OPTIMIZATION
(FR) PROFILS DE RÉFLEXION PERSONNALISÉS POUR UNE OPTIMISATION DE SYSTÈME D'AFFICHAGE RÉTRO-RÉFLÉCHISSANT
Abstract:
(EN) The present disclosure provides a display system that may comprise a retro -reflective screen having retro -reflective screen elements that reflect incident light and comprising at least one projector that (i) generates light characterizing an image or video and (ii) projects the light on the retro -reflective screen, wherein the projected light has a nominal profile. Additionally, the retro -reflective screen may reflect the light characterizing the image or video to a viewer in a manner such that an intensity profile of the light is offset away from the projector and has a uniform brightness profile within a field of view of the viewer with respect to the retro -reflective screen. The projected light may have an intensity drop-off that has at least a 200 % or 2x, or at least a 500% or 5x intensity reduction per 0.5 degrees outside of the nominal region.
(FR) La présente invention concerne un système d'affichage qui peut comprendre un écran rétro-réfléchissant ayant des éléments d'écran rétro-réfléchissant qui réfléchissent la lumière incidente et comprenant au moins un projecteur qui (i) génère une lumière caractérisant une image ou une vidéo et (ii) projette la lumière sur l'écran rétro-réfléchissant, la lumière projetée ayant un profil nominal. De plus, l'écran rétro-réfléchissant peut réfléchir la lumière caractérisant l'image ou la vidéo vers un observateur de manière à ce qu'un profil d'intensité de la lumière soit décalé par rapport au projecteur et présente un profil de luminosité uniforme dans un champ de vision de l'observateur par rapport à l'écran rétro-réfléchissant. La lumière projetée peut avoir une chute d'intensité qui a une réduction d'intensité d'au moins 200 % ou 2x, ou d'au moins de 500 % ou 5x par incrément de 0,5 degré à l'extérieur de la région nominale.
