Abstract

Cette invention concerne un système servant à produire un signal électrique à partir d'une représentation optique composite. Ce système comprend un écran à gain élevé 10, un projecteur d'arrière-plan 12, un projecteur de cible 14 et un projecteur de marquage 16. Une caméra de télévision 20 observe l'écran. La lumière transmise du projecteur 12 vers l'écran 10 est polarisée circulairement par un polariseur 18 et la lumière renvoyée par l'écran vers la caméra 20 est analysée par un analyseur opposé 22. L'écran 10 conserve la polarisation de la lumière qu'il réfléchit. Un agencement de ce type est utilisable notamment dans les systèmes d'entraînement au tir par armes à feu ou pièces d'artillerie.A system for producing an electrical signal from a composite optical representation is disclosed. This system includes a high gain screen 10, a background projector 12, a target projector 14, and a marking projector 16. A television camera 20 observes the screen. The light transmitted from the projector 12 to the screen 10 is circularly polarized by a polarizer 18 and the light returned by the screen to the camera 20 is analyzed by an opposing analyzer 22. The screen 10 maintains the polarization of the light that he thinks. An arrangement of this type can be used in particular in systems for training firing by firearms or artillery pieces.
