Abstract

EL PROCESO DE LA INVENCION ESTA DESTINADO A LA OBSERVACION DE IMAGENES HOLOGRAFICAS EXPUESTAS EN UN AMBIENTE LUMINOSO PARTICULARMENTE A PLENO DIA. SE CARACTERIZA EN QUE SE DISPONE CERCA DE UN HOLOGRAMA (101) UN OBJETO (201) CUYA NATURALEZA Y/O EXPOSICION ES TAL QUE LA LUZ PROCEDENTE DEL OBJETO OSCURO Y REFLEJADA POR EL HOLOGRAMA (101) TENGA UNA INTENSIDAD INFERIOR A LA DE LA LUZ QUE PROCEDE DE LA IMAGEN HOLOGRAFICA, EN QUE SE DA A ESTE OBJETO OSCURO (201) UNA POSICION Y UNA ORIENTACION TALES QUE EL REFLEJO (400) DE ESTE OBJETO (201) SE SUSTITUYE, PARA UN OBSERVADOR, POR LOS REFLEJOS LUMINOSOS NATURALES DEL AMBIENTE SUPERPUESTOS A LA IMAGEN HOLOGRAFICA (101).
