Abstract
A device intended to be associated, on the one hand, with a viewfinder, on the eyepiece side thereof, and, on the other hand, with a calculating mechanism, to form a system making it possible to determine at every instant that portion of a field sighted by the eye of an observer through the viewfinder. The device is arranged on the image side of the eyepiece of the viewfinder and includes a splitter element associated with a thick optical plate whose parallel faces are orthogonal to the optical axis of the finder.
