Abstract

PROCEDIMIENTO PARA SUPERVISAR EL ESPESOR DE UN REVESTIMIENTO, Y APARATO PARA LLEVAR A CABO DICHO PROCEDIMIENTO. EL PROCEDIMIENTO COMPRENDE DIRIGIR LUZ POLICROMATICA HACIA EL REVESTIMIENTO EN UNA PLURALIDAD DE POSICIONAR Y MEDIR LA INTENSIDAD DE LA LUZ REFLEJADA DEL MISMO. EN CADA POSICION, SE MIDE LA INTENSIDAD DE LUZ REFLEJADA PARA POR LO MENOS DOS LONGITUDES DE ONDA DE SUPERVISION DISCRETAS, Y ESTAS MEDICIONES SE PROCESAN PARA GENERAR UNA SEÑAL ELECTRICA QUE PUEDE COMPARARSE CON UNO O MAS VALORES UMBRAL PREDETERMINADOS Y CON LAS SEÑALES ELECTRICAS GENERADAS EN OTRAS POSICIONES, PARA PROPORCIONAR UNA INDICACION DE SI EL ESPESOR Y LA UNIFORMIDAD DEL REVESTIMIENTO SE ENCUENTRAN COMPRENDIDOS ENTRE VALORES DE TOLERANCIA PREDETERMINADOS. LAS DOS LONGITUDES DE ONDA DE SUPERVISION DISCRETAS SE ENCUENTRAN EN EL INTERVALO DE 400 A 480 NM (AZUL), DE 580 A 750 NM (ROJO), RESPECTIVAMENTE. SE PUEDE UTILIZAR TAMBIEN UNA TERCERA LONGITUD DE ONDA DE SUPERVISION DISCRETA, EN EL INTERVALO DE 480 A 580 NM (VERDE). LOS RESULTADOS DE LA SUPERVISION SE PUEDEN UTILIZAR PARA AJUSTAR EL PROCESO DE REVESTIMIENTO.
