Abstract
This paper deals with the design, fabrication and characterization of the first spherical artificial compound eye which is capable of obtaining resolvable images. Due to fabrication aspects it is based on a design that is slightly different from the natural archetype: it is comprised of an imaging microlens array and a pinhole array serving as receptors on separate spherical bulk lenses. The structuring of curved surfaces is possible by means of a modified laser lithography system. The ability to take images is proven and captured images are investigated with respect to the size of ghost-free field of view, resolution and angular sensitivity function.
