Abstract

Un propulsor de iluminacion para una pantalla de visualizacion de proyeccion que utiliza un TLP incluye un reflector que tiene puntos focales primero y segundo. Una fuente de radiacion electro-magnetica dispuesta cerca del primer punto focal del reflector emite rayos de radiacion que se reflejan desde el reflector hacia el segundo punto focal. Un TLP recolecta y transmite substancialmente la totalidad de la radiacion que converge en el segundo punto focal, ajustando la abertura numerica de la radiacion, pero curvando la superficie formada por las imagenes de la radiacion. Un SLP o una lente recolecta y transmite substancialmente la totalidad de la radiacion transmitida por el TLP, aplanando la superficie formada por las imagenes de la radiacion. Una lente condensadora recolecta y transmite substancialmente la totalidad de la radiacion transmitida por el elemento de retardo contorneado hacia un PBS y un sistema de proyeccion.
