Abstract

Un sistema óptico para visualizar una imagen incluye una guía de ondas (10) que tiene dos superficies principales (12, 14) que apoyan la propagación de la iluminación de imagen mediante reflexión interna. Una configuración de acoplamiento (16, 18) acopla la iluminación de imagen hacia el ojo del usuario. Un proyector de imágenes (20) se acopla para introducir la iluminación de imagen en la guía de ondas para que se propague mediante reflexión interna. La guía de ondas también contiene una región del multiplicador de haz simétrico, distinta de la región de acoplamiento, que tiene uno o más divisores de haz (24) internos a la guía de ondas y paralelos a sus superficies principales. El multiplicador de haz simétrico puede usarse para completar una imagen conjugada después de una configuración de acoplamiento compacto y/o puede usarse para llenar la guía de ondas con la imagen como una etapa intermedia (36) entre dos configuraciones de expansión de apertura óptica (32, 34).
