1. A helmet/head mounted projector system, comprising:
- a set of off-helmet mounted elements, including a background image generator, an area-of-interest (AOI) image generator, apparatus for combining the background image and the AOI image to form a combined image, said apparatus for combining said background image and said AOI image comprising a beam combiner, and apparatus for scanning the combined image into an input end of a fiber optic ribbon apparatus;
a set of on-helmet/head mounted elements, said set including a rotating polygon scanner and an optical apparatus for redirecting image light from an output end of said fiber optic ribbon apparatus onto said polygon scanner; and
a screen, said polygon scanner for redirecting said image light onto said screen for viewing by an observer.

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.
