Abstract

Un método y aparato para producir dentro de un área de formacion de imagen de una superficie cargada y sin formacion de bandas significativa, una disposicion de puntos de pixel que forman líneas de exploracion de imagen, incluyendo una línea de exploracion de imagen inicial. El método y el aparato incluyen un ROS para generar un numero par de haces de luz. El ROS incluye un montaje de polígono giratorio que tiene un numero plural de facetas "F" para cada deflexion del numero par de haces de luz sobre el área de formacion de imagen de la superficie cargada que forma los haces de exploracion para producir simultáneamente cada uno una línea de exploracion de imagen. El método y el aparato también incluyen un controlador para controlar el numero par de haces de luz, de tal manera que una separacion "d" del haz de exploracion es mantenida, donde "d" es igual a "F"-1 y de tal manera que el inicio de produccion de los puntos de pixel que forman las líneas de exploracion de imagen, los haces son desplazados en relacion con la línea de exploracion de imagen inicial y solamente una mitad del numero par de haces de luz es deflexionado sobre el área de formacion de imagen de la superficie cargada para formar cada uno una línea de exploracion de imagen.
