Abstract
Monocular or binocular viewing systems worn on the head of a user are provided. Each monocular assembly comprises a display and an optical assembly including an optical relay and a partially transparent optical combiner taking the form of an inclined curved plate, each optical assembly arranged to form a second image at infinity from a first image displayed by a display. The optics are to be crossed such that, in the case of a binocular system, if one optical combiner is placed in front of the right eye of the user, the optical relay and the corresponding display are placed in a forehead-facing position above the left eye of the user and under the optical combiner located on the left-hand side. This arrangement is obtained by judiciously choosing the geometric parameters of the various optical elements, their curvatures and the form of their surfaces.
