Abstract

MODIFICACIONES EN UN APARATO DE REPRESENTACION DE IMAGEN PARA CORREGIR LA DISTORSION EN LA TRAMA. CONSISTENTES EN QUE: SE INCLUYEN ELEMENTOS DE CORRECCION DE LA DISTORSION EN ALA DE GAVIOTA SENSIBLES A UNA PRIMERA SEÑAL, QUE SE REPITE A UNA FRECUENCIA DE LINEA, Y A UNA SEGUNDA SEÑAL, QUE SE REPITE A UNA FRECUENCIA DE CAMPO, PARA MODULAR LA CORRIENTE DE DESVIACION DE CAMPO DURANTE UN PERIODO DE DESVIACION DE LINEA, DENTRO DEL INTERVALO DE TRAZA DE DESVIACION DE CAMPO, DE MANERA QUE SE PRODUCE CORRECCION DE LA DISTORSION EN ALA DE GAVIOTA DE LA CORRESPONDIENTE LINEA DE EXPLORACION DE LA TRAMA; LOS ELEMENTOS DE CORRECCION DE LA DISTORSION EN ALA DE GAVIOTA MODULAN LA CORRIENTE DE DESVIACION DE CAMPO PARA PRODUCIR, APROXIMADAMENTE, DOS CICLOS DE MODULACION DURANTE EL INTERVALO DE DESVIACION DE LA LINEA, Y ADEMAS INCLUYEN UN MODULADOR DE PORTADORA SUPRIMIDA PARA DESARROLLAR UN VOLTAJE DE CORRECCION, POR ALA DE GAVIOTA, QUE SE APLICA AL CIRCUITO DE DESVIACION DE CAMPO Y QUE ES REPRESENTATIVO DE LA MODULACION DE LA PRIMERA SEÑAL, QUE SE REPITE A LA FRECUENCIA DE LINEA, MEDIANTE LA SEGUNDA SEÑAL, QUE SE REPITE A LA FRECUENCIA DE CAMPO. SE APLICAN A APARATOS CUYO TUBO TIENE UNA PLACA DE SUPERFICIE ESFERICA DE CONTORNO PLANO EN LOS QUE LA TRAMA ESTA SOMETIDA A LA DISTORSION EN ALA DE GAVIOTA.
