Abstract

Un matériau de film emploie un réseau bidimensionnel ordinaire de lentilles non cylindriques pour agrandir des micro-images, appelées icônes, pour former une image agrandie de manière synthétique au moyen dun rendement unifié dune multiplicité de systèmes dimages dicône/lentille individuelles. Le système micro-optique dagrandissement synthétique comprend un ou plusieurs espaceurs optiques, une micro-image formée sur un réseau planaire périodique dune pluralité dicônes images ayant un axe de symétrie autour dau moins un de ses axes planaires et positionnée sur lespaceur optique ou à proximité dudit espaceur et un réseau planaire périodique déléments de focalisation dicône image.
