Abstract

Aiming at the problem of mutual restriction between the quality of image and the equipment size in the current near-eye display (NED) system, we propose a NED system based on metasurface. We design a colorful NED system for MR/AR applications using all-dielectric metasurface and retina display technology. Based on the principle that metasurface can accurately control the wavefront, the system presents high-quality images while achieving lightweight and compact configuration like an ordinary pair of glasses. The semi-transparent metasurface with a size of 10mm×10mm is placed 15mm away from the eyes. Results show that the system could effectively enable monochromic and colorful object display onto the retina, and therefore allow clear images to be seen. With further optimization design, such system could provide a feasible solution for colorful NED system with miniaturization.
