An international team of researchers combined an X-ray laser and a lens-less pinhole camera to demonstrate the world's smallest and highest-resolution holograms of micron-size objects at nanometer resolution. By placing the camera's aperture very close to the object and using an array of hundreds of different-size pinholes, a computer was able to reconstruct the holograms, according to researchers in the United States, Germany and Sweden. The team displayed two images--a 3-D rendering of a single bacterium and a lithographic reproduction of Leonardo da Vinci's "Vitruvian Man"--to demonstrate the feasibility of nanometer-resolution holographic X-ray images of micron-size objects. The project showed that holographic X-ray images with femtosecond exposure times can freeze the action of atomic-scale operations--such as chemical actions--to advance nanotechnology
