Abstract

ESTE INVENTO ES UN SISTEMA INSPECTOR DE SUPERFICIES QUE INCLUYE UNA FUENTE DE LUZ (111) CON UN PROFUNDO MARGEN ENTRE CLARO Y OSCURO Y UNA CAMARA DE VIDEO (121) REFLEJANDO EL MARGEN REFLEJADO POR LA SUPERFICIE. LA INTENSIDAD DE LA LUZ DE LA FUENTE DE LUZ (111) ES CONTROLADA UTILIZANDO UN SENSOR DE INTENSIDAD DE LUZ (115). UN SISTEMA OPTICO (123) ENFOCA UNA IMAGEN DE LA FUENTE DE LUZ (111) EN LA CAMARA DE VIDEO CON SUFICIENTE PROFUNDIDAD DE ENFOQUE PARA INCLUIR LA SUPERFICIE (10) QUE DEBE SER INSPECCIONADA. LA DURACION DE LA EXPOSICION ESTA FIJADA PARA EVITAR IMAGENES BORROSAS SI LA SUPERFICIE SE ESTA MOVIENDO. UN APARTO DE CALCULO DE LA CALIDAD DE LA SUPERFICIE REALIZA, AL MENOS, UNA MEDIDA DE LA CALIDAD DE LA SUPERFICIE, COMO BRILLO, DISTINCION DE IMAGENES REFLEJADAS Y CORTEZA DE LA SUPERFICIE, DE LA SEÑAL DE VIDEO DE LA IMAGEN. EL APARATO DE CALCULO DE LA CALIDAD DE LA SUPERFICIE INCLUYE, PREFERIBLEMENTE, UN GRABADOR DE TRAMAS (130) Y UN ORDENADOR DIGITAL DE PROPOSITO GENERAL (140).
