Abstract

"SISTEMA DE PROJEçãO ESTEREOSCóPICA DE ALTO CONTRASTE". Um sistema de projeção estereoscópica é fornecido tendo dois canais, cada um tendo dois geradores de imagens LCOS que modula a luz em uma base de pixel por pixel. Um primeiro divisor de feixe de polarização é configurado para direcionar luz de uma primeira polarização em um gerador de imagens LCOS de primeiro estágio de primeiro canal e direcionar luz de uma segunda polarização, oposta à primeira polarização, no gerador de imagens LCOS de primeiro estágio de segundo canal. Um sistema de lente de relé direciona a saída dos geradores de imagens de primeiro estágio em um segundo divisor de feixe de polarização. O segundo divisor de feixe de polarização é configurado para direcionar luz da segunda polarização para o gerador de imagens LCOS de segundo estágio de primeiro canal e direcionar a luz da primeira polarização para o gerador de imagens LCOS de segundo estágio de segundo canal.
