Abstract

SE DESCRIBE UN ESCANER PARA LEER GRUPOS DE INFORMACION OPTICA BIDIMENSIONAL QUE INCLUYE UNA CARCASA PARA SOPORTAR UN SISTEMA FOTOSENSIBLE ASOCIADO A UNA CADENA OPTICA ADAPTADO PARA ENFOCAR LA INFORMACION OPTICA QUE SE ENCUENTRA EN EL SISTEMA. TAMBIEN HAY UNOS CONTROLES DE LA CADENA OPTICA Y DEL SISTEMA PARA CONTROLAR EL SISTEMA Y LA CADENA OPTICA DE TAL MODO QUE LA SALIDA DE LAS IMAGENES SELECCIONADAS DEL SISTEMA PUEDA SER PROCESADA A TRAVES DE UNOS ELEMENTOS DE RECONOCIMIENTO DE PATRONES. UNA PANTALLA MUESTRA Y RESALTA AQUELLAS IMAGENES EN LAS QUE SE HA DETECTADO QUE CONTIENEN INFORMACION OPTICA DECODIFICABLE. DE ESTE EL USUARIO OBTIENE AYUDA PARA PODER ENCONTRAR, RECONOCER, CONFIRMAR LA CAPACIDAD DE DECODIFICACION Y DECODIFICAR LAS IMAGENES CON INFORMACION OPTICA INCIDENTES EN EL SISTEMA.
