WIDE ANGLE HELMET MOUNTED DISPLAY SYSTEM

摘要

Compact head mounted monocular display system (100), mounted on top of a head-gear, having a large field of view comprising: a projector (124), and an elliptic visor(ll?), the projector (124) is mounted on the head gear, for projecting an image to a user of the head mounted display system(lOO), the projector (124) being located off the optical axis (132) of a selected single eye (112) of the user of the head mounted monocular display system, the elliptic visor (110) is mounted on the head gear, for reflecting the image from the projector (124) toward the selected single eye (112) of the user, the image being visible to the selected single eye (112) and invisible to the other eye of the user, the elliptic visor (110) being in the shape of a portion of a surface of an ellipsoid, the elliptic visor (110) being positioned in front of the selected single eye (112) of the user. The projector (124) includes an image source (102) for projecting the image, a relay optics assembly (104), optically coupled with the image source (102), for relaying the image, and a toroidal mirror(106), optically coupled with the relay optics assembly (104), for correcting the aberrations resulting from the off-axis orientation of the projector (124).
