Fig. 9.

AOSLO image of the foveal center of a healthy normal eye taken with broadband 840 nm light. The image is a sum of 279 frames from an individual video where variations in phase are not expected to occur, similar to the images in Fig. 6. A contiguous, close-packed mosaic is visible at the margins of the image but at the foveal center, the mosaic of cones is less clear. Despite the fact that cones are not resolved, the image still has high contrast, exhibiting a speckle-like appearance.
