Waveguide-based augmented reality displays: a highlightOACSTPCD

Augmented reality(AR),which emerged in the 1960s,remains a focal point of interest given its capacity to overlay the real world with digitally presented information through optical combiners.The prevalent combiner,commonly known as the waveguide in the AR literature,is prized for its compact design and generous eyebox—essential elements in human-centric technology.Nonetheless,these combiners encounter unique challenges in meeting various other requirements of the human visual system.This paper highlights a recent review of technological advancements and presents a forward-looking perspective on the future of AR technology.
