Abstract

Un sistema de conversión de polarización separa la luz desde una fuente de imagen no polarizada en un primer estado de polarización (SOP) y un segundo SOP ortogonal, y dirige la luz polarizada sobre la primera y segunda trayectorias de luz. El SOP de luz en solamente una de las trayectorias de luz es transformado a un estado ortogonal de manera que ambas trayectorias de luz tengan el mismo SOP. Un modulador de polarización modula de manera temporal la luz en la primera y segunda trayectorias de luz para el primero y segundo estados de polarización de salida. Primero y segundo lentes de proyección dirigen la luz en la primera y segunda trayectorias de luz hacia una pantalla de proyección para formar imágenes codificadas de polarización sustancialmente sobrepuestas. El modulador de polarización puede estar ubicado antes o después de los lentes de proyección. Las imágenes codificadas por polarización pueden ser visualizadas utilizando anteojos con adecuados filtros de polarización.
