The ‘inverted’ retina of the human eye can beemulated by multilayer gratings from polymer latexparticles located in the image plane of opticalsystems. This so called OPTO-RETINA provides v. Laueinterference patterns in visible light with atrichromatic characteristic containing,simultaneously, local spatiotemporal direction anddistance information, which are relevant to 3Dspatial vision and 4D spatiotemporal Fouriercorrelator-optical preprocessing in shape andmotion analysis.As a first step in the realization of OPTO-RETINAproperties the formation of hexagonally orderedmonolayers of polystyrene latex sphereswith diameters in the~μm range is reported and firstresults of diffraction and dispersion of white lightby these layers obtained by conoscopical opticalmicroscopy are presented.
