Abstract
A sight comprises an image carrier (D) presenting an exit aperture (P3) and forming, from an observed image (I), an intermediate image (I') at the focus (F) of an ocular comprised of a spherical mirror (M) with the same optical axis (XX') as that of the image carrier (D), with a holographic beam deflection element (H) being placed at the focus (F) of the spherical mirror (M). In accordance with the invention, the intermediate image (I') is formed on the focal surface (S) of the ocular, and the holographic beam deflection element (H) is disposed on a support resting on the focal surface (S) and, in association with the spherical mirror (M), conjugates stigmatically the exit aperture (P3) of the image carrier (D) with the exit aperture (P1) of the sight.
