摘要：

The 'inverted' retina of the human eye can be emulated by multilayer gratings from polymer latex particles located in the image plane of optical systems. This so called OPTO-RETINA provides v. Laue interference patterns in visible light with a trichromatic characteristic containing, simultaneously, local spatiotemporal direction and distance information, which are relevant to 3D spatial vision and 4D spatiotemporal Fourier correlator-optical preprocessing in shape and motion analysis. As a first step in the realization of OPTO-RETINA properties the formation of hexagonally ordered monolayers of polystyrene latex spheres with diameters in the mu m range is reported and first results of diffraction and dispersion of white light by these layers obtained by conoscopical optical microscopy are presented.
