Optical design of a confocal scanning laser ophthalmoscope based on adaptive optics

The optical design of a confocal scanning laser ophthalmoscope based on adaptive optics (AOSLO) is described in this paper. Spherical mirrors are used for pupil relay and astigmatism compensation. The main optical system achieves diffraction-limited performance through the entire scanning angle (6mm pupil, 3 degree on pupil plane).
