Title (EN) WIDE FIELD HEAD MOUNTED DISPLAY
(FR) VISIOCASQUE À CHAMP LARGE
Abstract:
(EN) An optical apparatus for display to a viewer has a concave spherical mirror that has a center of curvature at the viewer's pupil and that has a second radius of curvature. An image generation apparatus forms an image onto a spherical diffusive surface, wherein the spherical diffusive surface has a first radius of curvature that is substantially half the length of the second radius of curvature. A beam splitter is positioned along a principal axis of the concave spherical mirror and optically disposes the curved diffusive surface at the focal surface of the concave spherical mirror.
(FR) L'invention concerne un appareil optique pour fournir un affichage à un observateur, qui a un miroir sphérique concave qui a un centre de courbure au niveau de la pupille de l'observateur et qui a un second rayon de courbure. Un appareil de génération d'image forme une image sur une surface diffuse sphérique, la surface diffuse sphérique ayant un premier rayon de courbure qui est sensiblement la moitié de la longueur du second rayon de courbure. Un séparateur de faisceau est positionné le long d'un axe principal du miroir sphérique concave et dispose optiquement la surface diffuse incurvée au niveau de la surface focale du miroir sphérique concave.
