Abstract

EN DONDE UN CATODO OBTENIDO DE UN TRATAMIENTO ELECTROLITICO DE METALES ES ILUMINADO CON UNA FUENTE DE LUZ, TAL COMO UNA LAMPARA DE ALTA INTENSIDAD DE HALOGENO, UN TUBO FLUORESCENTE O UNA LAMPARA INCANDESCENTE, COLOCADA A UN ANGULO QUE ESTA ENTRE 0° Y 90° RESPECTO A LA LINEA CENTRAL DEL PLANO DE LA SUPERFICIE DEL CATODO; Y UNA IMAGEN DE LA SUPERFICIE ILUMINADA ES HECHA CON UNA CAMARA, TAL COMO UNA CAMARA FOTOGRAFICA O UNA CAMARA DE VIDEO INSTALADAS PERPENDICULARMENTE AL CENTRO DEL PLANO DE LA SUPERFICIE DEL CATODO, CUYA IMAGEN ES LUEGO TRANSMITIDA A UN DISPOSITIVO PARA PROCESAR IMAGENES, EN DONDE SOBRE LA BASE DE DICHA IMAGEN, SE DEFINEN SOMBRAS ARROJADAS POR LAS IRREGULARIDADES DE LA SUPERFICIE, CON EL FIN DE CLASIFICAR EL DEPOSITO UBICADO SOBRE EL CATODO PARA LA PROXIMA ETAPA DEL PROCESAMIENTO. LAS IMAGENES OBTENIDAS SON REGISTRADAS EN UN MICROPROCESADOR CONECTADO CON UN DISPOSITIVO DE PROCESAMIENTO DE IMAGENES, Y SON USADAS EN EL AJUSTE DE UN PROCEDIMIENTO ELECTROLITICO
