Abstract
A head mounted projector system with extremely high resolution. The system includes a retro-reflecting gain screen. The on-helmet apparatus of the system includes a truncated spherical mirror, a redirecting multi-faceted mirror and a small rotating polygon scanner. The system includes off-helmet apparatus including a background image source and an area-of-interest (AOI) image source. The background and AOI images are scanned into a linear ribbon array of fibers. To provide 20/20 visual acuity, one fiber per each 0.7 arc-minute field-of-view is used.
