The topographical array structures of photoreceptors were studied in avian retina. Each cone in avian retina has an oil droplet with colors distinctive to the types of cones. We have developed a procedure to determine the coordinates of the gravity centers of the cones, and to identify the types of cones using the particular absorption spectra of their oil droplets. The absorbance of monochromatic light was obtained through the measurements of the optical density of grayscale images taken by the monochromatic transillumination made by an interference filters. A set of computer programs were developed to conduct the acquisition of images, outline the oil droplets, locate the photoreceptors, measure the optical density and identify the cone types. Applying this procedure to the duck retinae, we could locate and identify all the cones in the examined area for the forthcoming mathematical analyses of the mosaic structures.
