Abstract
EL USO DE "AXICONS" LINEALES O ELEMENTOS OPTICOS SIMILARES EN UN SCANNER DE CODIGO DE BARRAS PRODUCE UN PUNTO DE EXPLORACION DE UN TAMAÑO QUE ESTA POR LO GENERAL EN RELACION CON LAS DIMENSIONES DE CARACTERISTICAS DE LA INFORMACION EXPLORADA, DONDE EL TAMAÑO DEL PUNTO PERMANECE SUSTANCIALMENTE CONSTANTE PARA DISTANCIAS VARIABLES ENTRE EL SCANNER Y EL SIMBOLO SOBRE UNA GAMA CONSIDERABLE DE DISTANCIAS. LOS ELEMENTOS OPTICOS DE ESTE TIPO PRODUCEN UN FORMATO DE DIFRACCION QUE COMPRENDE UN LOBULO CENTRAL Y UN NUMERO DE ANILLOS QUE CIRCUNDAN AL LOBULO CENTRAL. SE DISPONE DE UNA ABERTURA PARA LIMITAR EL HAZ Y ASI EL NUMERO DE ANILLOS EN EL FORMATO QUE REALMENTE ALCANZA EL SIMBOLO DURANTE LA EXPLORACION. LA EXTENSION DEL HAZ LIMITADO Y DEL ANGULO DE INCLINACION FRONTAL DE FASE PRODUCIDO POR EL ELEMENTO OPTICO SE SELECCIONAN PARA OBTENER UNA RESOLUCION DESEADA, LA CUAL SE REFIERE A LA DENSIDAD DE SIMBOLOS QUE EL SCANNER HA DE LEER, Y PARA OBTENER UNA GAMA DE TRABAJO CONVENIENTE. LA INVENCION PROPORCIONA TAMBIEN UN DISPOSITIVO EMISOR DE LUZ MODULAR, INCLUYENDO UN MODULO EMISOR DE LUZ UNIVERSAL Y UN CONJUNTO OPTICO, INCLUYENDO EL "AXICON" Y ABERTURA, MONTADO SOBRE EL MODULO PARA ADAPTAR LAS CARACTERISTICAS OPTICAS DE LUZ DESDE EL MODULO PARA ADAPTARSE A LOS REQUERIMIENTOS DE UNA APLICACION DE EXPLORACION PARTICULAR.
