Abstract
The general field of the invention is that of optical viewing systems comprising a display and a tilted optical plate arranged above this display and forming therewith substantially a dihedron. The system according to the invention comprises means for adjusting the reflection coefficient of the said tilted optical plate along an axis perpendicular to the axis of the dihedron and up to a variable height so as to ensure the total reflection of a first part of the image displayed by the display and the partial reflection of a second part of the image displayed by the display, complementary to the first part. The insertion of optical components between the display and the optical plate makes it possible to modify the distance of the display image reflected by the optical plate.
