Abstract
"ARQUITETURA DE PROJETOR DE DOIS ESTáGIOS". Um sistema de projeção de luz projeta uma imagem compreendendo uma matriz de pixels de luz tendo luminância modulada. O sistema de projeção inclui um primeiro gerador de imagens configurado para modular uma faixa de luz em uma base de pixel por pixel proporcional a valores de escala de cinza fornecidos para cada pixel da imagem para fornecer uma primeira matriz de saída. Um segundo gerador de imagens é posicionado e configurado para receber a primeira matriz de saída de pixels de luz modulada e modular os pixels de luz modulada individuais do dito primeiro gerador de imagens em uma base de pixel por pixel proporcional a um segundo valor de escala de cinza fornecido para cada pixel da imagem.
