Abstract
This invention has incorporated projective optics and phase conjugate material thus eliminating the requisite use of an external phase conjugate material to provide a see-through head mounted projective display. A key component of the invention is the use of optical imaging technology in combination with projective optics to make this revolutionary technology work. In previous head mounted projective displays the phase conjugate material had to be placed in the environment to display images, but in this invention one is not limited to the use of an external phase conjugate material but further extends its use to outdoor see-through augmented reality to produce images using the see-through head mounted projective display system. Furthermore, this invention extends the use of projective head mounted displays to clinical guided surgery, surgery medical, an outdoor augmented see-through virtual environment for military training and wearable computers.
