A binocular head mounted display system is shown utilizing an aspheric lens (20, 22) in each of the user's right-eye and left-eye optical paths. The aspheric lens (20 or 22) is formed with a number of concentric zones for controlling the distance at which an image of displayed information is projected from the user and to minimize distortions across the virtual image. The distance between each lens (20 or 22) and its respective display (24 or 26) is independently variable. Further, the distance between the optical system as a whole and the user's eyes is variable.
L'invention concerne un système d'affichage binoculaire du type lunettes dans lequel on utilise une lentille asphérique (20, 22) prévue dans les champs optiques de l'oeil droit et gauche de l'utilisateur. Ladite lentille asphérique (20 ou 22) est constituée de plusieurs zones concentriques conçues pour ajuster la distance à laquelle une image d'informations affichées est projetée par rapport à l'utilisateur et minimiser la distorsion dans l'image virtuelle. La distance entre chaque lentille (20 ou 22) et son affichage respectif (24 ou 26) varie individuellement. De plus, la distance entre le système optique dans son intégralité et les yeux de l'utilisateur est variable.
