Abstract

EL HAZ DE RADIACION EMITIDO POR UNA FUENTE POLICROMATICA DE DIMENSION FINITA INCIDE SOBRE UN SISTEMA DE MICROLENTES QUE TIENEN LA FUNCION DE CONVERGER Y DIVERGER EL HAZ EN UNA PLURALIDAD DE MICROHACES DIRIGIDOS HACIA UNA MATRIZ QUE CONTIENE MICROFILTROS COLOREADOS. UNA VEZ PASADOS LOS MICROFILTROS, LA RADIACION ALCANZA UNA MATRIZ DE MICROCORTADORES QUE UN CONTROLADOR PUEDE SELECCIONAR DE FORMA INDEPENDIENTE ENTRE SI PARA GENERAR IMAGENES.
