Abstract

"SISTEMA DE PROJEçãO". Um sistema de projeção que pode ajustar o equilíbrio da cor da luz incidente é proporcionado. O sistema de projeção inclui uma fonte de luz, um filtro espacial, um separador ótico, uma unidade de rolagem de imagens, uma válvula de luz, e uma unidade de lentes de projeção. O filtro espacial possui uma fenda para ajustar um ângulo divergente ou etendue da luz emitida a partir da fonte de luz. O separador ótico separa a luz que passa através do filtro espacial de acordo com a cor da luz incidente. A unidade de rolagem de imagens possui um ou mais discos-lente espiral, os quais são formados mediante arranjo em forma espiral de células de lentes cilíndricas, giram, e fazem a rolagem de imagens dos feixes de cor separados por meio do separador ótico. A válvula de luz processa a luz que passa através da unidade de rolagem de imagens de acordo com um sinal de imagem e forma uma imagem. A unidade de lentes de projeção amplia a imagem formada sobre a válvula de luz e projeta a imagem ampliada por sobre uma tela.
