Abstract

"DISPOSITIVO DE EXIBIçãO POR PROJEçãO". Trata-se de um dispositivo de exibição por projeção que inclui uma primeira até uma terceira unidades de fonte de luz, respectivamente, de diferentes cores, um prisma dicróico cúbico (X-cube prism) para combinar os percursos dos primeiro até terceiro feixes de luz, um modulador ótico para modular seq³encialmente os primeiro até terceiro feixes de luz de acordo com informações de imagem, e uma unidade de lentes de projeção para ampliar e projetar os feixes de luz modulados sobre uma tela. Cada uma das primeira até terceira unidades de fonte de luz inclui pelo menos um módulo ótico. O módulo ótico inclui um colimador possuindo uma primeira superfície refletora de formato parabólico, e uma fonte de luz compacta localizada na proximidade de um ponto focal da primeira superfície refletora.
