Abstract

L'invention concerne un procédé et un dispositif pour l'analyse d'objets transparents. Selon ce procédé, le faisceau optique d'éclairage se réfléchit une première fois sur un miroir oscillant ou tournant M pour former l'image S' de la source S sur l'objet transparent à analyser A, et le faisceau ainsi modulé en intensité par la transparence dudit objet A se réfléchit une seconde fois sur ledit miroir tournant ou oscillant M, le système optique complexe étant agencé de manière à former sur un plan P situé devant le récepteur fixe une image fixe S" de la source et une image mobile A' de l'objet transparent. Application comme tireuse, comme tireuse-agrandisseuse, pour la réalisation de clichés améliorés et trames destinés à l'imprimerie, et pour la télétransmission d'images.
