Abstract
The ability of simulated bipolar cells (BC) of the human central fovea to resolve images is studied with a two-bar stimulus using a resolution index (RI) as a measure of resolvability. RIs are determined for intensity and chromatic contrasts using all combinations of white, black, red, yellow, green, and blue lights. arious cone matrixes and BC receptive field organizations are studied for orientation preference by using two-bars oriented either 0, 45, 90, or 135 degrees to the horizontal axis of the retina. Nonpreference for orientation, i.e. RI does not change with bar orientation, varies with matrix type, and receptive field organization. For a given orientation RI increases asymptotically as bar width or length, or gap between the bars increases. Systematic changes in RI occur with systematic changes in contrast. For most color pairs there are residual RIs at isoluminance.
