Abstract

sistema óptico e sistema óptico para exibir uma imagem a um olho de um usuário. trata-se de um sistema óptico para exibir uma imagem que inclui um guia de ondas (10) tendo duas superfícies principais (12, 14) que suportam a propagação da iluminação da imagem por reflexão interna. uma configuração de acoplamento para fora (16, 18) acopla a iluminação de imagem em direção ao olho do usuário. um projetor de imagem (20) é acoplado de modo a introduzir iluminação de imagem no guia de ondas de modo a se propagar por reflexão interna. o guia de ondas também contém uma região multiplicadora de feixe simétrica, distinta da região de acoplamento para fora, tendo um ou mais divisores de feixe (24) internos ao guia de ondas e paralelos às suas superfícies principais. o multiplicador de feixe simétrico pode ser usado para preencher uma imagem conjugada após uma configuração compacta de acoplamento para dentro e/ou pode ser usado para preencher o guia de ondas com a imagem como um estágio intermediário (36) entre duas configurações de expansão de abertura óptica (32, 34).
