    Abstract: An optical system for use in helmet mounted displays that consists of an image source, electronics that predistort the image emanating from the projector, a means for correcting for optical aberration that may be a lens or a fiber optic taper, and a reflective surface composed of a plurality of reflective surface elements with conic geometries. Light from the projector, corrected for optical aberrations, is directed into the first reflective surface element. Light from the first reflective surface element is reflected into a second reflective surface element and thereafter into the eye.
