Abstract

Un sistema óptico que incluye un elemento óptico guía de luz (LOE) con un primer y segundo conjuntos (204, 206) de superficies parcialmente reflectantes y mutuamente paralelas en diferentes orientaciones. Ambos conjuntos de superficies parcialmente reflectantes se ubican entre superficies externas paralelas principales. Un tercer conjunto de superficies al menos parcialmente reflectantes (202), desplegadas en la región de acoplamiento de entrada, reciben la iluminación de la imagen inyectada desde un proyector (2) con una abertura óptica que tiene un primer ancho en el plano y dirigen la iluminación de la imagen a través de la reflexión de al menos parte de la iluminación de la imagen en el tercer conjunto de facetas al menos parcialmente reflectantes hacia el primer conjunto de facetas parcialmente reflectantes con una abertura óptica efectiva que tiene un segundo ancho mayor que el primer ancho.
