  • a concave mirror;

    two contiguous reflecting mirrors whose juncture is located at or near the conjugate point of the image plane of the entrance pupils of the eyes of an observer, said reflecting mirrors being positioned and orientated for separately directing light rays from right and left stereo views, respectively, of a common object onto the concave mirror such that the light rays are focussed after reflection from the concave mirror;

    the concave mirror comprising means for focussing the right and left view light rays directed from the reflecting mirrors into a right and left real image in space between the concave mirror and the eyes of an observer, both real images being superimposed in apparent registration in the same plane at their point of focus to the eyes of an observer positioned beyond their point of focus for being viewed by an observer on or off axis to the concave mirror.
