Abstract

L'invention concerne la formation d'images visibles de contraste élevé à partir d'images de charges électrostatiques. Elle se rapporte à une chambre de formation d'images dans laquelle l'image formée par des particules 61 d'un agent de virage dépose en fonction de l'image de charges électrostatiques, a un contraste élevé, car les particules 61 sont de type fluorescent, et un filtre 67 ne laisse passer que la lumière au maximum d'émission des particules 61. Application à la formation d'images radiographiques de contraste élevé.
