1. A virtual display apparatus based on a cross-cavity optical configuration comprising:

  • a support means attached and connected to a near-eye optic assembly comprising;

    a near-eye optic attached and connected to a near-eye optic holder attached and connected to a near-eye optic support bracket attached and connected to said support means;

    furthermore said support means is additionally attached and connected to an adjacent folding optic assembly comprising;

    an adjacent folding optic attached and connected to an adjacent folding optic holder attached and connected to an adjacent folding optic support bracket attached and connected to said support means;

    furthermore said support means is additionally attached and connected to an image source assembly comprising;

    a real image source, in communication with electrical and electronic means, attached and connected to an image source holder attached and connected to an image source support bracket attached and connected to said support means; and

    a magnifying stage holder attached and connected to said image source support bracket;

    and additionally attached and connected to a magnifying stage in close proximity to said real image source;

    wherein said magnifying stage is disposed for simultaneous illumination reception from said real image source for first intermediate image formation and illumination transmission to said adjacent folding optic and is selected to provide primary magnification of said real image source;

    wherein said adjacent folding optic provides a light deflection means and is disposed for simultaneous illumination reception from said magnifying stage for second intermediate image formation and illumination redirection to said near-eye optic, and additionally selected to provide supplemental magnification of said real image source; and

    wherein said near-eye optic provides a light deflection means, positioned in the normal peripheral field of view for unobstructed forward vision attainment, and is disposed for simultaneous illumination reception from said adjacent folding optic for observable virtual image formation and illumination redirection to the user'"'"'s eye; and

    additionally selected to provide supplemental magnification of said real image source.
