Abstract

UN SISTEMA DE PROYECCION COMPRENDE UNA PLURALIDAD DE LCD (LIQUID CRYSTAL DISPLAY STAL LIQUIDO) 41, 42, 43 QUE SE IRRADIAN CON SUBHACES (21, 22, 23) COLOREADOS. LOS SUBHACES NO SON INCIDENTES PERPENDICUARMENTE SOBRE LOS LCD, CON LO QUE LOS HACES REFLEJADOS (24, 25, 26) NO COINCIDEN CON LOS HACES INCIDENTES. LOS SUBHACES SE ORIGINAN DESDE UN HAZ (20) DE LUZ BLANCA QUE SE DIVIDE EN SUBHACES COLOREADOS MEDIANTE ESPEJOS DE COLORES SELECTIVOS (31, 33). LOS MISMOS ESPEJOS SE UTILIZAN PARA COMBINAR LOS HACES REFLEJADOS (24, 25, 26) A UN HAZ (27) DE PROYECCION. UN SEPARADOR (80) DE HACES SEGUN EL ANGULO SE DISPONE PARA REALIZAR UNA SEPARACION ESPACIAL ENTRE LOS HACES INCIDENTES Y EL HAZ REFLEJADO. EL SEPARADOR (80) DE HACES SEGUN EL ANGULO ESTA DISPUESTO EN TAL FORMA QUE EL ANGULO EN EL QUE EL HAZ (20) ES INCIDENTE SOBRE LOS ESPEJOS (31, 33) SELECTIVOS DE COLORES ES IGUAL AL ANGULO EN EL QUE LOS SUBHACES REFLEJADOS (24, 25, 26) SON INCIDENTES SOBRE ESTOS ESPEJOS.
