Abstract

UN SISTEMA DE PROYECCION PARA PROYECTAR UNA IMAGEN DE VIDEO FORMADA POR ELEMENTOS DE IMAGEN SOBRE UNA PANTALLA (54) DISPONE AL MENOS DE UNA FUENTE (10;20;30) DE LUZ DE INTENSIDAD VARIABLE QUE EMITE UN RAYO DE LUZ Y UN DISPOSITIVO (44,46) DE ESCANEADO QUE EXPLORA EL RAYO DE LUZ PARA LA ILUMINACION DE LOS ELEMENTOS DE IMAGEN SOBRE LA PANTALLA (54). SE DISPONE DE OPTICA (50) DE TRANSFORMACION CON AL MENOS DOS ETAPAS ENTRE EL DISPOSITIVO (44,45) DE ESCANEADO Y LA PANTALLA (54), SIENDO CORREGIDAS DE ACUERDO CON EL TEOREMA DE LA TANGENTE PARA ELIMINAR DISTORSIONES OPTICAS. LA OPTICA DE TRANSFORMACION EN FUNCIONAMIENTO DISPONE AL MENOS DE DOS ETAPAS OPTICAS. LA ETAPA OPTICA PRIMERA GENERA UN PLANO TOTAL INTERMEDIO REPRODUCIDO SOBRE LA PANTALLA MEDIANTE LA ETAPA OPTICA SUBSECUENTE.
