Abstract: The general field of the invention is that of heads-up display systems comprising at least one display and one optical guide comprising a first image guide comprising a plurality of first internal semi-reflecting plates, inclined with respect to a first plane. The heads-up display system according to the invention comprises: an oculometer designed to detect the position of the pupil of the eye of an observer; at least one of the said first plates comprising a processing with programmable reflectivity, the said reflectivity depending on the position and/or of the orientation of the ocular pupil detected by the oculometer, in such a manner as to reflect the image of the display towards the said pupa and only towards the latter. The display system can comprise a second image guide perpendicular to the first.

Abstract: The general field of the invention is that of optical guides for collimated images comprising a first and a second image conductor functioning by total reflection, each conductor comprising a plurality of plates that are planar, semi-reflective, mutually parallel and inclined with respect to the plane of the external faces of the image conductors. The two conductors are arranged so as to deliver a collimated image to a large pupil. The optical guide according to the invention comprises an optical beam doubler element having substantially the shape of a rectangular parallelepiped. In its basic version, it comprises four external planar facets, two internal semi-reflective planar mirrors, said mirrors being mutually perpendicular, a planar entrance face intended to receive a collimated image, and an exit face adhesively bonded to the injection section of one of the image conductors. The invention also relates to the whole of the display device associated with this optical guide.
