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.
Claims7
A mountable optical system, comprising:
- (a) a retrocollimator optic with a clamshell geometry formed by two curved surfaces with conic section cross sections which intersect at a curved line thus forming a continuous inner surface mounted so as to intercept an optical image and thereafter reflect the image into the eye of the observer;
- and
- (b) a means for projecting an optical image into said retrocollimator optic.
