DOI: 10.1109/tbc.2017.2786022
Abstract: It is often difficult to show deep 3-D scenes with sufficient quality on 3-D displays with light-ray reconstruction, such as light-field and integral 3-D displays, because their depth-reconstruction range is restricted. Scenes with substantial depth… read more here.

DOI: 10.1364/ol.383428
Abstract: It is difficult to maintain high transverse resolution over an increased depth range using miniature probes for optical coherence tomography (OCT) due to the rapid divergence of light and the space limitation. To solve this… read more here.
