Abstract

Lichtwegaufbau eines Reflexions-Flüssigkristallprojektors, aufweisend: DOLLAR A eine Lichtquelle zur Lichteinleitung entlang einer Richtung (0, 0, 1); DOLLAR A einen ersten dichroitischen Würfel, der eine erste Beschichtung mit einem Normalvektor (1, 0, 1) aufweist, wobei die erste Beschichtung grünes Licht durchläßt und rotes Licht und blaues Licht reflektiert; DOLLAR A einen zweiten dichroitischen Würfel, der an einer Seite des ersten dichroitischen Würfels angebracht ist, von wo das rote Licht und das blaue Licht abgestrahlt werden, wobei der zweite dichroitische Würfel eine zweite Beschichtung mit einem Normalvektor (1, 1, 0) aufweist, wobei die zweite Beschichtung das blaue Licht durchläßt und das rote Licht reflektiert; DOLLAR A einen dritten dichroitischen Würfel, der an einer Seite des ersten dichroitischen Würfels angebracht ist, von wo das grüne Licht abgestrahlt wird; DOLLAR A ein grünes Flüssigkristallanzeige-(LCD)-Feld, das an einer Seite des ersten dichroitischen Würfels angebracht ist, um das grüne Licht durchzulassen: DOLLAR A ein blaues LCD-Feld, das an einer Seite des zweiten dichroitischen Würfels angebracht ist, um das blaue Licht durchzulassen; DOLLAR A ein rotes LCD-Feld, das an einer Seite des zweiten dichroitischen Würfels angebracht ist, um das rote Licht durchzulassen.
