Abstract
Performance improved spectacle-mounted ocular display apparatus, where the addition of a movable relay mirror mounting assembly provides for image focusing and placement, framing, and orientation/alignment by permitting both translational and rotational movement of the relay mirror. This movement of the relay mirror mounting assembly in turn causes an optical change in the distance of the image from the eye. The performance improvement results from the ability to change the distance between image source and the relay mirror thereby providing a means for increasing the range of image placement and focus adjustment.
Claims4
A spectacle mounted ocular displayed apparatus, the performance improvement comprising the addition to a movable relay mirror mounting assembly, said assembly comprising
- at least two continuous contact tracks integral with, and in close proximity and attached to, a spectacle frame in a generally parallel relationship to the bridge of said spectacle frame, and
- a bracket with runner means of engaging and maintaining at least three contact points with at least two of said contact tracks, furthermore said bracket integral with, and in close proximity and attached to, the relay mirror support arm at the end opposing the relay mirror,
- whereby translational movement of said bracket along the length of said tracks causes a change in the distance of said relay mirror from an object on the temple of said spectacle frame which in turn causes an optical change in the focus of the image from the eye.
