Inspiration for new technology is everywhere, even in the fossils of prehistoric creatures it seems. Scientists have developed a nanophotonic light field camera with extreme depth of field capabilities, based on the eye of the extinct trilobite, Dalmanitina socialis.
Ask any palaeontology (or just about any 5 year old) and they will tell you that the trilobite was one of the first animals to develop complex eyes. Very complex it turns out. What made it unique was the fact that it could focus on both near and far objects simultaneously. Most eyes and cameras simply cannot achieve this dual focus feat.
