Abstract
Patente de Invenção de "SISTEMA DE PROJEçãO DE VìDEO", para a projeção sobre uma tela (54) de uma imagem de vídeo composta por pontos de imagem, com pelo menos uma fonte de luz (10, 20, 30) com intensidade variável que emite um feixe de luz e um dispositivo de deflexão (44; 46) que deflete o feixe de luz para iluminaçào dos pontos de imagem na tela (54), uma óptica transformadora de pelo menos dois estágios (50) é disposta entre o dispositivo de deflexão (44; 46) e a tela (54), que é corrigida livre de distorção de acordo com a condição tangencial. à óptica transformadora por seu lado abrange pelo menos dois estágios, sendo que o primeiro estágio gera um plano intermediário de imagem que é reproduzida na tela pelo (s) estágio (s) seguinte (s).
