The spatial arrangement of the L and M cones in the central fovea of the living human eye.
Experiments designed to estimate the placement of L and M cones in fovea centralis of the living human eye are presented. Hyperacuity performances for two observers were measured for the full and the separate L and M cone submosaics using 2-dot chromatic stimuli on cone-selective adapting backgrounds. Simulated performances, based on an ideal observer model, were generated for all possible mosaics by varying L and M cone relative numerosity and spatial configuration. The best match between the simulated and measured performances determined the solution mosaic. Each observer's solution mosaic contained more L than M cones, randomly arrayed as assessed by statistical tests.
