Abstract
We demonstrate the feasibility of a multimodal AO flood-illumination ophthalmoscope, able to provide both bright-field and dark-field images. The multimodality was made possible by integrating a digital micromirror device (DMD) at the illumination path to project a sequence of complementary high-resolution patterns into the retina. Owing to the given system, and the proposed acquisition/processing pipeline, we were able, at the same time, to: (1) obtain up to four-fold contrast improvement in bright-field modality when imaging highly scattered structures such as PRs and NFL; and (2) to visualize, through phase contrast images, translucent retinal features such as capillaries, red blood cells, vessel walls, ganglion cells, and PRs inner segment.
