Abstract

An optical apparatus includes a system of optical components capable of operating in a scanning laser ophthalmoscope (SLO) mode and an optical coherence tomography (OCT) mode. The system of optical components includes a first optical module for the SLO mode, a second optical module for the OCT mode, and a first scanning device. The first optical module for the SLO mode includes a first source adapted to provide a first imaging beam for the SLO mode and a first detection device configured to receive a first signal associated with a first image of a retina of an eye. The second optical module for the OCT mode includes a second source adapted to provide a second imaging beam for the OCT mode and a second detection device configured to receive a second signal associated with a second image of the retina. The first scanning device is configured to move the first imaging beam along the retina in the slow axis of the SLO mode to acquire the first image and (ii) to move the second imaging beam along the retina in the fast axis of the OCT mode to acquire the second image.
