Abstract

We have studied a prototype of human retina which is based on a round thin-film photoluminescent concentrator coupled at its edge to the circular Si-photodiodes. This passive integrated optoelectronic device can perform most important function of peripheral human vision: determination of position of the light source and motion detection. For 12-mm radius film we have got a spatial resolution 13 micrometers in the linear range +/- 5 mm. By stacking several films each with a different absorption characteristic it is possible to realize color sensitive element and, therefore, to perform full functions of human retina.
