Fig. 6.

Both images are of the same photoreceptor mosaic in a healthy normal eye. Both images are a registered sum of 100 frames from a single video. Variations in phase were not expected to have occurred over the course of one video and the addition of multiple frames is used here to increase the S:N of the image. The left image is taken with coherent 660 nm light and the right is taken with low coherent 680 nm light. The cone reflectance in the right image is much less variable, and the image reveals more of the contiguous close-packed cone photoreceptor array. The FFT of the image (lower left inset) reveals a better defined ring corresponding to the periodic cone array for the low-coherent image.
