Abstract:
1. A head-mounted viewing system, comprising; a display device having a substantially planar surface; an objective lens assembly extending along an optical axis and located substantially adjacent the display device through which light propagates from the display device along the optical axis through an exit aperture of the objective lens assembly; a split-field reflector substantially adjacent the exit aperture of the objective lens assembly that directs substantially half of the light along a right optical path to form an image on a right exit pupil and substantially the other half of the light along a left optical path to form an image on a left exit pupil; a folding apparatus to correctly orient the image to the respective right and left exit pupil; a right intermediate image plane located along the right optical path and a left image plane located along the left optical path; and exit pupil enhancement structure located along the right and left optical paths to prescriptively enlarge each right and left exit pupil.
