Abstract

Cet objectif de viseur périscopique est destiné à être monté sur une caméra solidaire d'un ensemble de contrôle de tir utilisé sur un avion. Le faisceau 1 de la lumière incidente tombe en premier lieu sur un prisme à réflexion totale 2 qui le renvoie vers le bas à travers un ensemble optique. Cet ensemble est composé d'une lentille convergente 3 et suivie par une autre lentille bi-concave 4. Une troisième lentille bi-convexe 5 complète cet ensemble. La lumière traverse ensuite un diaphragme à iris 6 pour tomber sur une lame semi-réfléchissante plane 7 qui en renvoie une partie vers un autre groupe optique compose d'un doublet 8 suivi par une lentille divergente bi-concave 9. Après avoir traversé cet ensemble, la lumière tombe sur le film 12. L'autre partie de la lumière ayant traversé la lame semi-réfléchissante traverse ensuite une lentille en forme de ménisque concave convexe 10 pour tomber sur une cellule photoélectrique 11. Ce dispositif est applicable aux viseurs cinématographiques utilisés dans l'aviation.
