Abstract

Procedimiento para la reproducción de imágenes televisadas en el cual la superficie de una capa rectora dentro de un sistema de óptica estriada es deformadas en correspondencia con la señal de imagen, por un rayo catódico que barre la capa rectora en líneas yuxtapuestas y es utilizada para la dirección de la luz, caracterizado pro el hecho de que el rayo catódico deposita sobre la capa rectora a lo largo de las líneas cargas eléctricas en forma de tiras, correspondiendo la anchura de las tiras transversalmente a la línea, en cada punto de la imagen, al la magnitud de la señal de imagen, en el sentido de aumentar la anchura a medida que decrece la claridad del punto de la imagen.
