Seeing depth through a single lens

摘要

Microscopists may soon be able to create a 3D image through a single lens, without moving the camera, thanks to researchers at the Harvard School of Engineering and Applied Sciences (SEAS). The technique relies only on computation and mathematics-with no fancy hardware or lenses. The technique could offer a new and accessible way to create 3D images of translucent biological materials. Principal investigator, Kenneth B. Crozier, John L. Loeb Associate Professor of the Natural Sciences, said: "If you close one eye, depth perception becomes difficult. Your eye can focus on one thing or another, but unless you also move your head from side to side, it's difficult to gain much sense of objects' relative distances. If your viewpoint is fixed in one position, as a microscope would be, it's a challenging problem."
