Abstract
Light field displays have been primarily targeted for auto-stereoscopic displays: with multiple views across a wide viewing angle, people from different perspectives are able to see slightly different contents. Recently, by showing a High-Angular-Resolution light field to a single viewer, new applications and algorithms are developed to enhance the visual experience. Vision-correcting displays let eyes with aberrations see the display in sharp focus without wearing eye-glasses; this is enabled by approximating the inverse aberrations using a dense light field. Another application of the High-Angular-Resolution light field solves the Vergence-Accommodation-Conflict by supporting focus cues in a VR headmount. We showed that, by exploring the compressibility of near-eye light fields, perceived spatial resolution of the display can be greatly enhanced when compared to prior work. © 2016, Society for Imaging Science and Technology (IS&T).
