Optomechanical design of the ultra-compact SLO/OCT handheld probe. a, Optical design and system schematic of the handheld probe. All optical components are labelled and described in the legend. Blue and red text in the schematic correspond to components used for imaging in SLO or OCT mode, respectively. b, Spot diagrams (colour coded for 3 wavelengths spanning 805–870 nm) for both SLO and OCT illumination on the retina of a model eye spanning a 7° FOV. Airy disks are shown by black circles. c, Photorealistic rendering of the handheld probe mechanical design. Scale bars represent 8 μm in b and 2 cm in c.
