Computer Monitor In Eyeglasses

We have all seen science fiction ideals of computer displays concealed in eyeglasses. One of the earlier spectacle-based designs was created by David Bettinger and disclosed in US Patent 4,806,011. Advances in fabrication technologies are now allowing complicated surface profiles to be manufactured. Exploitation of a complicated surface profile leads to low element count designs. Researchers at the University of Central Florida, CREOL/College of Optics & Photonics have designed and fabricated a computer monitor in eyeglasses that uses sophisticated surface profiles to achieve a compact design. The current specifications include an 8mm exit pupil, 20-degree field of view, 15mm eye clearance, and a resolution of 1.5 arcminutes.
