“…In VR optics, the lens arrays (LAs), especially micro-LA (MLA) or lenticular-LA (LLA), are frequently used to present the 3D digital content, realizing the light field display or integral imaging display. − Because these refraction-based elements refract all incident light without the selectivity, they are not suitable for the AR displays that require the OST capability. On the other hand, well-fabricated LA PPHOEs can be adopted to create 3D AR displays, since the PPHOEs can selectively diffract the desired light while transmitting others.…”

Augmented reality (AR) and virtual reality (VR) are emerging as a next-generation display platform, surpassing conventional flat panel displays. The AR/VR technologies are garnering considerable attention from both industry and academia as they provide immersive user experiences and smooth interaction between the real and digital worlds. The current AR/VR displays, however, still face several challenges including limited field of view, small eye-box, conflict between the vergence and accommodation, bulky form factor, and heavy weight. This paper aims to provide a comprehensive view of optical elements of AR/VR displays, emphasizing how they enhance the performance and user experience of the AR/VR displays. Various techniques are explained in the following two principal aspects: AR/VR displays based on (1) holographic optical elements and metasurfaces, and (2) combined usage of optical elements. In each section, the characteristics and principles of the optical components are briefly explained. Then, their recent applications addressing the limitations of the conventional AR/VR displays are introduced.
