Title (EN) HEAD-MOUNTED DISPLAY APPARATUS EMPLOYING ONE OR MORE REFLECTIVE OPTICAL SURFACES
(FR) VISIOCASQUE EMPLOYANT UNE OU PLUSIEURS SURFACES OPTIQUES RÉFLÉCHISSANTES
Abstract: front page image
(EN)Head-mounted displays (100) are disclosed which include a frame (107), an image display system (110) supported by the frame (107), and a reflective surface, e.g., a free-space, ultra-wide angle, reflective optical surface (a FS/UWA/RO surface) (120), supported by the frame (107). In certain embodiments, the reflective surface (120) produces spatially-separated virtual images that are angularly separated by at least 100, 150, or 200 degrees. Methods and apparatus for designing reflective optical surfaces, including FS/UWA/RO surfaces, for use in head-mounted displays (100) are also disclosed.
(FR)L'invention porte sur des visiocasques (100) qui comprennent une monture (107), un système d'affichage d'image (110) supporté par la monture (107), et une surface réfléchissante, par exemple une surface optique réfléchissante en espace libre à ultra-grand angle (surface FS/UWA/RO) (120), supportée par la monture (107). Dans certains modes de réalisation, la surface réfléchissante (120) produit des images virtuelles séparées spatialement qui sont séparées angulairement par au moins 100, 150 ou 200 degrés. L'invention porte également sur des procédés et un appareil de conception de surfaces optiques réfléchissantes, comprenant des surfaces FS/UWA/RO, destinées à être utilisées dans des visiocasques (100).
