16 ABSTRACT OF THE DISCLOSURE Disclosed is an optic device designed to enable an observer to look simultaneously at what is normally in his visual field and at a collimated image that is introduced so as to be superimposed on his visual field. The optic device has a plate with parallel faces in which the light rays coming from an image generator, through an access point, get propagated by total reflection on the parallel faces. A slab, formed by a stacking of plane mirrors, reconcentrates the light rays and directs them towards two successive, semi-reflecting mirrors which reflect them partially towards the observation pupil. The semi-reflecting mirrors are in the visual field of an observer's eye placed at the observation pupil.
