Images of photoreceptors mosaic (1000 registered and averaged frames) from one subject, at two foveal eccentricities–(a) 1° temporal and (b) 2° temporal–acquired in flood illumination mode at 1 kHz with closed-loop AO correction. Both show the characteristic hexagonally tiled cone mosaic, with the cones more tightly packed closer to the fovea. (c) Average radial profile of the cone mosaic at 1°T and 2°T. The arrows show the periodicity of each cone mosaic.
