Fig. 3.

Example of AO images obtained using the 60 D model eye with an artificial “retina” made from a white piece of paper printed with ink spots, together with an intraocular scatterer. All images shown are the average of 50 frames and linearly stretched to fill the colormap for display purposes. Uniform (a) and Speckle (b) images were obtained with the scatterer in place and with uniform and speckle illumination, respectively. HiLo images were generated using two different values for the depth-of-field (DOF), with DOFx4 in (c) and DOFx8 in (d), with the circled areas showing greater enhancement of higher frequency details for the DOFx4 HiLo image in (c), and greater enhancement of lower frequency details for the DOFx8 HiLo image in (d) (see Fig. 4 for Fourier analysis). The Ideal image (e), which was obtained without the scatterer, is also shown for comparison. Scale bar = 50 µm.
