Abstract

CABEZA ELECTRONICA PARA LA CAPTACION DE SIGNOS GRAFICOS. CONSTA DE UNOS MEDIOS DE ILUMINACION QUE ABARCAN LA ZONA DE POSIBLE PRESENTACION DE LOS SIGNOS, MEDIOS PARA EL ENFOQUE DE LA IMAGEN PRODUCIDA POR EL SIGNO ILUMINADO SOBRE SENSORES QUE CONVIERTEN LAS SEÑALES LUMINOSAS EN SEÑALES ELECTRICAS ANALOGICAS, Y CONVERTIDORES ANALOGICOS/DIGITALES. ESTOS CONVERTIDORES POSEEN UN PRIMER BLOQUE GENERADOR DE UMBRAL QUE PROPORCIONE A UN BLOQUE COMPARADOR UNA PRIMERA SEÑAL QUE DEPENDE DE LA REFLECTIVIDAD DEL SOPORTE SOBRE EL QUE SE PRESENTAN LOS SIGNOS GRAFICOS. EL BLOQUE COMPARADOR, CON UNA SEGUNDA SEÑAL QUE AMPLIFICA LAS DIFERENCIAS EN LA SEÑAL ANALOGICA, PRODUCE UNA TERCERA SEÑAL DIGITAL REPRESENTATIVA DE LOS SIGNOS GRAFICOS. DE APLICACION EN LINEAS DE TRATAMIENTO AUTOMATICO DE CORRESPONDENCIA Y, EN GENERAL, PARA LA CAPTACION DE SIGNOS GRAFICOS.
