Augmented reality and virtual reality displays: emerging technologies and future perspectives

🤖 Plain-English Summary

With rapid advances in high-speed communication and computation, augmented reality (AR) and virtual reality (VR) are emerging as next-generation display platforms for deeper human-digital interactions. Afterwards, we discuss how these devices help enhance the AR and VR performance, with detailed description and analysis of some advanced architectures.

🔑 Key Findings

• Nonetheless, to simultaneously match the exceptional performance of human vision and keep the near-eye display module compact and lightweight imposes unprecedented challenges on optical engineering.
• Fortunately, recent progress in holographic optical elements (HOEs) and lithography-enabled devices provide innovative ways to tackle these obstacles in AR and VR that are otherwise difficult with traditional optics.
• In this review, we begin with introducing the basic structures of AR and VR headsets, and then describing the operation principles of various HOEs and lithography-enabled devices.
