Abstract

DISPOSITIVO DE MEDIDA DE LA CONVERGENCIA ESTATICA Y DINAMICA, ASI COMO METODO DE AJUSTE DE LA UNIDAD DE CONVERGENCIA ESTATICA EN TUBOS DE IMAGEN DE COLOR, DEL TIPO DE MASCARA DE SOMBRA, Y BOBINAS DE DEFLEXION. CONSISTE EN UNA CELULA FOTOSENSIBLE CON DOS PARTES FOTOSENSIBLES SIMETRICAS, CON RESPECTO AL CENTRO DE LA CELULA, Y UNOS ELEMENTOS OPTICOS QUE VISUALIZAN UNA PARTE DE LA PANTALLA DE IMAGEN SOBRE LA CELULA FOTOSENSIBLE, FORMANDO EL CONJUNTO UN DETECTOR (65) QUE ESTABLECE LA DIFERENCIA DE INTENSIDAD ENTRE LAS PARTES SIMETRICAS DE LA CELULA FOTOSENSIBLE Y MEDIANTE UN MICROORDENADOR (66) CONTROLA LA CORRIENTE CONTINUA A TRAVES DE LAS BOBINAS DE DEFLEXION (67) PARA CENTRAL EL HAZ DE ELECTRONES (9) SOBRE LA CELULA FOTOSENSIBLE, EL MICROORDENADOR CONTROLA TAMBIEN LA UNIDAD (68) DE AJUSTE DE CONVERGENCIA ESTATICA (70) FORMADO POR UN ANILLO MAGNETIZABLE ALREDEDOR DE LOS CAÑONES DE ELECTRONES (8, 9 Y 10), LA MAGNETIZACION SE REALIZA A TRAVES DE UNA UNIDAD DE MAGNETIZACION (71).
