Abstract:
1. A transparent component adapted to transmit, through a surface of said component, light rays originating from a scene situated on a first side of the component to form a first image representative of said scene and visible on a second side of the component, the component being characterized in that it comprises: a set of active elements juxtaposed parallel to the surface of the component and each switchable between a transparent individual state and a reflecting individual state; an addressing system connected to each active element and suitable for controlling a switching of said element; at least one light passage opening; and light transmission means arranged between the passage opening and the active elements, so that each active element can establish a light path between said light passage opening and one of the sides of the component when said active element is in the reflecting state; the addressing system being further adapted so that a reduced number of active elements are simultaneously in the reflecting state, so that said first image appears permanently through the component, and the light transmission means and the active elements being further arranged to conjugate optically points of an additional optical field situated on one and the same side of said light transmission means as the light passage opening with respective points situated outside and at a distance from the component, on one of the first or second sides of said component.
