20. A two-element, off-axis imaging system for an eyeglass-based display device, the imaging system comprising:
-
a microdisplay that generates images for an observer; a lens that aids in correcting optical aberration, the lens having an aspheric surface; a diffractive optical element that corrects chromatic aberration; a fold mirror that reflects the images generated by the microdisplay to the lens; and a partial mirror that defines an x-y polynomial surface that reflects the images to an eye of an observer; wherein the imaging system comprises no other optical elements. - View Dependent Claims (21)
