Abstract

We enhanced the capabilities of an Adaptive Optics Flood Illumination Ophthalmoscope to achieve multimodal imaging. The control of the illumination with a digital micromirror device, combined with a wide field of view and a light data processing, allows us to improve the brightfield contrast with a pseudo-confocal mode and to visualize transparent retinal structures with phase contrast imaging. We achieved to get from a single sequence of acquisition, four wide field images, each corresponding to one type of the following imaging modes: contrast-enhanced brightfield, darkfield, offset aperture and split-detection imaging.
