Abstract
A mounting assembly for a vision enhancement device and associated vision enhancement display, the assembly comprising a display mounted to an arm positionable in front of the user'"'"'s eye, a base member for receiving a cradle for the vision enhancement device and for attaching to a head-mounting platform, and one or more intermediate members for connecting the arm to the cradle. In one embodiment, the mounting system comprises one or more mechanisms for aligning the display optical axis with the vision enhancement device optical axis and with the user'"'"'s line of sight, one or more mechanisms for orienting the vision enhancement device within multiple degrees of freedom without changing the alignment of the display optical axis with the device optical axis, and one or more mechanisms for toggling the display between an in-use position to at least one storage position, and, optionally, between right eye and left eye positions.
