Augmented reality technology is a new display technology that integrates virtual digital information with real physical information and has become an important research field in global information technology. Near‐eye display devices are an important part of augmented reality. At present, traditional optical devices are widely used in near‐eye equipment, but the optical performance of the equipment is limited and the volume is large, making it difficult to meet the market's needs for thinness and high performance. With the development of micro‐nano processing technology, metasurfaces composed of artificial sub‐wavelength scale units, which are both ultra‐thin and can regulate arbitrary light fields, will become a new idea for the development of new near‐eye display devices...
