See-Through Conformable Holographic Metasurface Patches for Augmented Reality

Current requirements for augmented reality (AR) applications demand the use of dedicated AR glasses, which often need custom prescription lenses or contact lenses to correct common visual impairments, thus limiting AR's broader experiences. Here, an innovative methodology for the design, fabrication, and comprehensive analysis of a flexible, reflective-type holographic metasurface patch designed for AR applications is presented. By fabricating a conformable metasurface on a transparent and flexible substrate, a prototype of AR eyeglasses is successfully created, capable of transforming everyday eyewear into AR glasses. The prototype is tested under both indoor and outdoor conditions, proving its effectiveness in delivering immersive AR imaging presentations. The metasurface's compact size does not interfere with normal vision. This approach increases the relevance and applicability of AR technology by making AR experiences accessible to a wider audience.
