Abstract

Un multiplicador de apertura óptica incluye una primera guía de ondas óptica (10) que tiene una sección transversal rectangular y que incluye superficies parcialmente reflectantes (40) en un ángulo oblicuo a una dirección de elongación de la guía de ondas. Una segunda guía de ondas óptica (20), incluyendo también superficies parcialmente reflectantes (45) en un ángulo oblicuo, se acopla ópticamente con la primera guía de ondas óptica (10). Una imagen se acopla en la primera guía de ondas óptica con una dirección inicial de propagación en un ángulo de acoplamiento oblicuo avanza por la reflexión interna cuádruple a lo largo de la primera guía de ondas óptica, con una proporción de la intensidad de la imagen reflectada en las superficies parcialmente reflectantes de manera que se acoplan en la segunda guía de ondas óptica y se propaga a través de la reflexión doble dentro de la segunda guía de ondas óptica, con una proporción de intensidad de la imagen reflectada en dichas superficies parcialmente reflectantes de manera que se dirigen hacia el exterior desde una de las caras paralelas como una imagen visible.
