Micron-sized X-ray Holograms
BERKELEY, Calif., Aug.4, 2008 – A group of scientists have produced two of the brightest, sharpest x-ray holograms of microscopic objects ever made. Working at both the Advanced Light Source (ALS) at the US Department of Energy’s Lawrence Berkeley National Laboratory, and at FLASH, the free-electron laser in Hamburg, Germany, this group is boasting a method that is thousands of times more efficient than previous x-ray holographic methods. Inspired by an ancient technique known as the pinhole camera, the x-ray hologram (made...
