It fits on the head of a pin, has no lens or moving parts, can be made for just a few cents, and yet it can take a photo of the Mona Lisa in which she’s actually sort of recognizable ... it’s called the Planar Fourier Capture Array (PFCA), and it’s a tiny camera developed at New York’s Cornell University. Although you might choose not to use it for photographing your child’s birthday party, it could come in quite handy in the fields of science and technology.
