Abstract

METODO Y APARATO PARA DESORDENAR Y PARA VOLVER A ORDENAR SIMBOLOS DE CODIGO DE BARRAS. SE DESCRIBRE UN APARATO Y EL METODO CORRESPONDIENTE PARA DESORDENAR UN PANORAMAGRAMA PARALACTICO QUE ES UNA DISECCION LINEATICULAR DE UN CODIGO DE BARRAS FORMADO ORDENANDO EL CODIGO DE BARRAS DE ACUERDO CON UN RETICULO FORMADO POR UNA PLURALIDAD DE ELEMENTOS DE ENFOQUE CONTIGUOS PARALELOS DISPUESTOS CON UNA FRECUENCIA ESPACIAL SUPERIOR A LA FRECUENCIA ESPACIAL MODULAR DEL CODIGO DE BARRAS. EL METODO INCLUYE EL POSICIONAMIENTO DE DICHO PANORAMAGRAMA EN UNA POSICION CONTIGUA A LA SUPERFICIE OPUESTA DE UNA PANTALLA TRANSPARENTE A LA LUZ QUE TIENE UNA PLURALIDAD DE ELEMENTOS LINEALES PARALELOS DE FORMA ALARGADA INCLUYENDO SUPERFICIES DE ENFOQUE DISPUESTAS EN COMUN A LO LARGO DE UNA PRIMERA SUPERFICIE DE LA PANTALLA, ESTANDO ADAPTADA LA FRECUENCIA ESPACIAL DE ESTOS ELEMENTOS LINEALES ESTEN DISPUESTOS DE MANERA SUSTANCIALMENTE PARALELA RESPECTO A LAS LINEAS DE LA DISECCION LINEATICULAR.
