A Helmet Mounted Display (HMD) system, to be mounted on a helmet of a user, includes a tinted visor, coupled with the helmet, located in front of the face of the user when the tinted visor is in an operative position. The tinted visor further includes a patch, which is located in front of an eye of the user. The patch has greater light transmission than the rest of the tinted visor. The HMD system includes an image generator, coupled with the helmet, generating an image to be displayed to the user. The HMD system further includes an optical combiner, coupled with the helmet, and located substantially on the optical axis of the user's eye. The combiner reflects the generated image toward the eye, and transfers light rays of an outside scene toward the eye. |

1. A Helmet Mounted Display (HMD) system, to be mounted on a helmet of a user, said HMD comprising:
a tinted visor, coupled with said helmet, said tinted visor being located in front of the face of said user when said tinted visor is in an operative position, and outside of the field of view of said user when said tinted visor is in a stowed position, said tinted visor further including a patch, said patch being located in front of an eye of said user, said patch having greater light transmission than the rest of said tinted visor; an image generator, coupled with said helmet, generating an image to be displayed to said user; an optical combiner, coupled with said helmet and separated from said tinted visor, said optical combiner being located externally to said tinted visor, said optical combiner intersects the optical axis of said eye, said optical combiner reflecting said generated image toward said eye, said optical combiner transferring light rays of an outside scene toward said eye; and a tint cover, located between said optical combiner and said outside scene, such that light rays from said outside scene pass through said tint cover, said optical combiner, and through said patch before reaching said eye. |
