Abstract

L'invention se rapporte à la correction de distorsion d'un intensificateur d'image comportent un écran primaire (4) destiné à recevoir un premier rayonnement et unécran secondaire (5) émettant un second rayonnement fonction du premier rayonnement. L'intensificateur d'image comporte en outre des moyens (16) pour projeter sur l'écran primaire (4) une mire (41) de localisation réalisée à l'aide d'un troisième rayonnement (17) et l'écran secondaire (5) émet une image fonction de la mire (41) de localisation.
