Abstract
SE DETERMINA LA CALIDAD OPTICA DEL VIDRIO FLOTADOR POR SOMBROSCOPIA EN UN LUGAR APROPIADO DE LA LINEA DE FABRICACION DE DICHO VIDRIO. LA IMAGEN ESTA REGISTRADA POR UNA CAMARA DE VIDEO Y EVALUADA MEDIANTE UN TRATAMIENTO DE IMAGEN NUMERICO CON EL FIN DE DETERMINAR EL PERFIL DE DENSIDAD LUMINOSA. EL PERFIL DE REFRACCION ES CALCULADO A PARTIR DEL PERFIL DE DENSIDAD LUMINOSA Y ES REPRESENTADO Y EVALUADO NUMERICA O GRAFICAMENTE.
