Abstract

SE PRESENTA UN METODO Y UN APARATO PARA LEER CODIGOS DE BARRAS GRABADOS DIRECTAMENTE SOBRE UNA SUPERFICIE PULIDA DE UN PRODUCTO, EN PARTICULAS DE COMBUSTIBLE NUCLEAR EN EL CUAL EL PRODUCTO SE POSICIONA DE TAL FORMA QUE LA PARTE DE SU SUPERFICIE QUE TIENE EL CODIGO DE BARRAS GRABADO DIRECTAMENTE EN LA MISMA, SE DISPONE DE FORMA ADYACENTE A UNA SUPERFICIE DIFUSORA DE LUZ Y ENTRE DICHA SUPERFICIE Y UN LECTOR DE LUZ. UN HAZ DE LUZ LASER SE DIRIGE SOBRE EL CODIGO DE BARRAS QUE LLEVA LA SUPERFICIE DEL ARTICULO DE TAL FORMA QUE LA LUZ SE REFLEJA SOBRE EL SOBRE LA SUPERFICIE DIFUSORA DE LUZ Y DESDE ESTA ULTIMA HASTA EL LECTOR DE LUZ. LA SUPERFICIE DIFUSORA DE LUZ SE DISPONE EN UN ANGULO DE ALREDEDOR DE 30 (GRADOS) CON RELACION AL CAMINO DEL HAZ DE LUZ DIRIGIDO AL CODIGO DE BARRAS QUE SOPORTA LA PARTE DE LA SUPERFICIE DE TAL FORMA QUE SOLO EL 25% DE LA LUZ ES REFLEJADA POR LA SUPERFICIE DIFUSORA DE VUELTA AL LECTOR DE LUZ. EL LECTOR DE LUZ ESTA ADAPTADO PARA PODER OSCILAR ENTRE UN GENERADOR DE LUZ DESPLAZADO ANGULARMENTE Y LAS POSICIONES DE RECEPCION DE LUZ PARA GENERAR Y DIRIGIR RESPECTIVAMENTE EL HAZ DE LUZ HACIA EL CODIGO DE BARRAS QUE ESTA SOPORTADO EN LA PARTE DE LA SUPERFICIE DEL PRODUCTO Y PARA LEER LA LUZ REFLEJADA DESDE LA SUPERFICIE DIFUSORA DE LUZ.
