Abstract

DISPOSITIVO ÓPTICO E MÉTODO PARA FABRICAR UM DISPOSITIVO ÓPTICO. Um substrato transparente tem duas faces paralelas e guia a luz de imagem colimada pela reflexão interna. Um primeiro conjunto de superfícies internas é disposto dentro do substrato oblíquo às faces paralelas. Um segundo conjunto de superfícies internas mutuamente paralelas dispostas dentro do substrato paralelas, intercalado com e em relação de sobreposição com o primeiro conjunto de superfícies internas. Cada uma das superfícies internas do primeiro conjunto inclui um primeiro revestimento tendo uma primeira característica de reflexão para ser pelo menos parcialmente reflexiva a pelo menos um primeiro subconjunto de componentes de luz incidente. Cada uma das superfícies internas do segundo conjunto inclui um segundo revestimento tendo uma segunda característica de reflexão complementar à primeira característica de reflexão para ser pelo menos parcialmente reflexiva a pelo menos um segundo subconjunto de componentes de luz incidente. Os conjuntos de superfícies internas cooperam para refletir todos os componentes da luz dos primeiro e segundo subconjuntos.
