Multidimensional en-face OCT imaging of the retina. [PDF]

, 2009
Fast T-scanning (transverse scanning, en-face) was used to build B-scan or C-scan optical coherence tomography (OCT) images of the retina. Several unique signature patterns of en-face (coronal) are reviewed in conjunction with associated confocal images ...

Noninvasive imaging of the thirteen-lined ground squirrel photoreceptor mosaic. [PDF]

, 2016
Ground squirrels are an increasingly important model for studying visual processing, retinal circuitry, and cone photoreceptor function. Here, we demonstrate that the photoreceptor mosaic can be longitudinally imaged noninvasively in the 13-lined ground ...

Accessible digital ophthalmoscopy based on liquid-lens technology [PDF]

, 2015
Ophthalmoscopes have yet to capitalise on novel low-cost miniature optomechatronics, which could disrupt ophthalmic monitoring in rural areas. This paper demonstrates a new design integrating modern components for ophthalmoscopy.
