Abstract

UN APARATO DE MEDIDA DE LA CONVERGENCIA PARA UN CRT EN COLOR (1) COMPRENDE UN SENSOR DE LUZ (4) QUE ESTA COLOCADO SOBRE LA PANTALLA (2) DEL CRT (1) QUE SE VA A PROBAR, UNA CPU (8), Y UN GENERADOR DE MODELO (15) QUE PRODUCE UNA DIVERSIDAD DE LINEAS LUMINESCENTES DE UN COLOR PRIMARIO QUE SE VA A VISUALIZAR SOBRE UN AREA (S1) DE LA PANTALLA (2) Y UN AREA PLANA QUE ES UN COMPUESTO DE LOS OTROS DOS COLORES PRIMARIOS QUE SE VAN A VISUALIZAR SOBRE OTRA AREA (S2) DE LA PANTALLA. LAS LINEAS SE DESPLAZAN A UNA CADENCIA DADA A LO LARGO DEL AREA DESIGNADA (S1) DE LA PANTALLA (2), CAMBIANDO SUCESIVAMENTE EL COLOR DE LAS LINEAS VISUALIZADAS A CADA UNO DE LOS COLORES PRIMARIOS. EL SENSOR DE LUZ (4) RECIBE INFORMACION DE INTENSIDAD LUMINOSA DEL MODELO GENERADO Y LA CPU (8) CALCULA UN VALOR DE ERROR DE CONVERGENCIA BASADO EN LOS DATOS DE INTENSIDAD LUMINOSA. EL APARATO INCLUYE ADEMAS UNA CARACTERISTICA DE AUTO-INSPECCION POR LA QUE SE EJECUTA EL PROCESAMIENTO PARA MEDIDAS SUCESIVAS DEL MISMO COLOR PRIMARIO.SI LOS VALORES DE CADA UNA DE LAS MEDIDAS SON IDENTICOS, SE SUPONE QUE EL SISTEMA ESTA FUNCIONANDO NORMALMENTE, PERO SI HAY VARIACION, SE PUEDE DIAGNOSTICAS FUNCIONAMIENTO ANORMAL.
