Paper Abstract
A digital light projector is implemented as an integrated illumination source and scanning element in a confocal nonmydriatic retinal camera, the DLP-Cam. To simulate scanning, a series of illumination lines are rapidly projected on the retina. The backscattered light is imaged onto a 2-dimensional rolling shutter CMOS sensor. By temporally and spatially overlapping the illumination lines with the rolling shutter, confocal imaging is achieved. This approach enables a low cost, flexible, and robust design with a small footprint. Qualitative image comparison with commercial non-mydriatic SLOs and fundus cameras shows comparable fine vessel visibility and contrast.
