Figure 2.

(A) First, a cross scan with visible red light and 0.01 to 0.02 mW incident power was used for alignment to the fovea centralis. (B) Then, a hybrid radial-raster scan with broadband visible light (shown as green) and 0.1 to 0.13 mW incident power was used for data acquisition. Approximate scan locations are shown on grayscale fundus photographs.
