Abstract

Un sistema de visualización que comprende un primer expansor de pupila de guía de ondas; el primer expansor de pupila de guía de ondas comprende un puerto de entrada, un puerto de salida, un primer par de superficies paralelas y un segundo par de superficies paralelas; el primer par de superficies paralelas es ortogonal al segundo par de superficies paralelas; el primer par de superficies paralelas está dispuesto para guiar la luz de un campo de luz difractado o divergente (por ejemplo, holográfico) desde el puerto de entrada al puerto de salida por reflexión interna entre ellos; una primera superficie del primer par de superficies paralelas es parcialmente transmisiva-reflexiva de manera que el campo de luz se divide en cada reflexión interna y una pluralidad de réplicas del campo de luz se transmite a través de una región de la primera superficie que forma el puerto de salida; el segundo par de superficies paralelas también está dispuesto para guiar con luz el campo de luz desde el puerto de entrada al puerto de salida mediante al menos una reflexión interna.
