Abstract
An optical device for projecting light beams that is able to interact with a pixelated light source comprising a plurality of selectively activatable emitting elements. The device successively includes, in the direction of the path of the light rays, a first optical unit, a pupil and a second optical unit. The first optical unit includes an output diopter located at a first distance (d) from the pupil, and the second optical unit includes an input diopter interface located at a second distance (d) from the pupil, the second distance (d) being substantially identical to the first distance (d). The first unit includes a converging lens, and the second unit includes a doublet of lenses one of which is made of flint glass and the other of which is made of crown glass.
