Abstract

DISPOSITIVO PARA CORREGIR LA DEFORMACION GEOMETRICA. EN EL SISTEMA DE REPRODUCCION DE IMAGEN EN DONDE LOS TUBOS FORMADORES DE IMAGENES SE COMBINAN CON UNIDADES DE BARRIDO, DA UN ERROR REMANENTE, ESTA CARACTERIZADO, PORQUE LAS LINEAS NIVELADAS SON REPRODUCIDAS EN FORMA INVERTIDA CON RESPECTO AL MODULO DE REFERENCIA. PARA ELIMINAR ESTE ERROR, SE PROPONE AUMENTAR UNA CORRIENTE EN FORMA DE DIENTE DE SIERRA DE FRECUENCIA DE LINEA A UN DEVANADO VERTICAL DE LA UNIDAD DE BARRIDO. TUBOS FORMADORES DE IMAGENES CON UNIDADES DE BARRIDO INTEGRADAS PERTENECIENTE A TELEVISORES EN COLORES.
