Prospects and challenges in augmented reality displays
Abstract
Augmented reality (AR) displays are attracting significant attention and efforts. In this paper, we review the adopted device configurations of see-through displays, summarize the current development status and highlight future challenges in micro-displays. A brief introduction to optical gratings is presented to help understand the challenging design of grating-based waveguide for AR displays. Finally, we discuss the most recent progress in diffraction grating and its implications. Keywords: Near-eye displays, See-through display, Augmented reality, Micro-displays, Bragg gratings
