Abstract
The invention relates to an optical imager including a waveguide having a front face and a rear face and into which light beams emitted by an optical element of a light-beam generator system are introduced via an inlet surface and are directed towards the eye of the wearer through said rear face by means of an optical arrangement, so as to make it possible to view information content, said front and rear faces of the waveguide presenting a property of angular selectivity in reflectance and transmittance, and said optical arrangement comprising a Mangin mirror and a quarterwave plate between said front face and said mirror. In the invention, said quarterwave plate is encapsulated between said mirror and another element.
