Abstract

An augmented reality display system based on an ultra-thin see-through stacked metasurface near eye visor is proposed. We use the unique capabilities of plasmonic metasurfaces to control light at the subwavelength scale and design a see-through diffractive element that can project a full color image from a micro-display into the eye. This element is comprised of three metasurface layers, each designed to diffract only a specific wavelength and keep the rest of the visible spectrum unaffected. By implementing this layered design we can harness the advantages of diffractive optics and reduce their chromatic aberrations. We present here the design process of the proposed metasurface near eye visor and validate it by fabricating and testing a proof of concept sample.
