Fig. 1.

Scaled (1:1) schematic layout of our non-planar design flood-illumination AO ophthalmoscope, flattened for visualization. All angles and distances are to scale. Representations of optical components are for illustrative purposes only. Two illumination arms are built in: the “wide-field illumination arm” and the “AO illumination arm”. The two arms can be switched by using the three flip mirrors marked with an asterisk (*FM). DPSS: diode-pumped solid-state laser. SPR: spatial phase randomizer. M: flat mirrors. BS: plate beam splitter. FM: flip mirrors. CM: curved mirrors. P: pupil planes conjugate to the wavefront sensor and deformable mirror. DM: Mirao 52d deformable mirror. WFS: wavefront sensor. Note that SPR1 (coupled to imaging light) was switched on and off for HiLo imaging (see description below), and SPR2 (coupled to wavefront sensing light) was left on throughout the experiment. Scale bar: 100 mm.
