New Nanotechnology Imaging

Caption: Highly coherent X-rays from synchrotron sources can be used for imaging nanomaterials in 3-D at tens of nanometer of spatial resolution. This image shows a monochromatic hard X-rays patterns from a single crystal gold particle, which produces a speckle-like fringe image. Inverting such "diffraction images" under certain conditions can result in a high-resolution distribution of the electron density (amplitude) and strain of the lattice structure (phase shift).
