Abstract

EL PROCEDIMIENTO CONSISTE EN CALCULAR (E1-E4), EN UN ESPACIO GEOMETRICO DE TRES DIMENSIONES, UN CONJUNTO DE IMAGENES BIDIMENSIONALES REPRESENTATIVAS DE UN OBJETO VIRTUAL SEGUN PUNTOS RESPECTIVOS DIFERENTES. EL OBJETO VIRTUAL ESTA REPRESENTADO POR DATOS DIGITALES ALMACENADOS EN UN ORDENADOR. SE CALCULAN UNOS HOLOGRAMAS (E5-E6) PARA RESPECTIVAMENTE LAS IMAGENES BIDIMENSIONALES SEGUN UNA TECNICA DE TRANSFORMACION RAPIDA COMPLEJA, COMO UNA TECNICA DE TRANSFORMACION DE FOURIER. LOS HOLOGRAMAS SE YUXTAPONEN A CONTINUACION (E7) PARA FORMAR UN HOLOGRAMA DIGITAL DEL OBJETO, QUE SE REPRODUCE (E8) FISICAMENTE POR UN MODULADOR ESPACIAL DE LUZ. ILUMINANDO EL MODULADOR ESPACIAL DE LUZ POR UNA FUENTE COHERENTE, SE OBTIENE ASI UNA IMAGEN EN TRES DIMENSIONES DEL OBJETO.
