Abstract: A scanning laser ophthalmoscope (SLO) for imaging the retina of an eye comprises a source (12) of collimated light, a scanning device (14, 16, 1328, 1319), a scan transfer device (20) and a detector (1310). The scan transfer device has a first focus (16) at which an apparent point source is provided and a second focus (24) at which an eye (524, 1324) may be accommodated. The scan transfer device transfers a two-dimensional collimated light scan from the apparent point source into the eye. An optical coherence tomography (OCT) system (900) is combined with the SLO, the OCT system providing OCT reference and sample beams. The OCT sample beam (902) propagates along the same optical path as of the SLO collimated light through the scan transfer device. An aberration compensator (1204, 1316) automatically compensates for systematic aberrations and/or changes in wavefront introduced by scanning elements and the scan transfer device as a function of scan angle.
