Abstract

L'addition a pour objet une amélioration du dispositif selon le brevet principal. Une lentille de convergence constante est introduite dans le système optique. Cette lentille est composée d'un ensemble électromagnétique-électrostatique. Le courant d'excitation de la lentille électromagnétique entraîne une rotation de l'image du diaphragme dans le plan objet L'addition a les mêmes applications que le brevet principal.
