Abstract

A foveated optical system has non-uniform resolution across its field of view. Typically, the resolution of such a lens is peaked in the center region of field of view, such as in the human eye. In biological systems this is often a result of localized depressions on the retina called foveae. Birds of prey, or raptors, have two foveae in each eye, each of which accounts for a localized region of high magnification within the raptor's field of view. This paper presents an analysis of the bifoveated vision of raptors and presents a method whereby this unique optical characteristic may be achieved in an optical system using freeform optics and aberration correction techniques.
