Micron-sized X-ray Holograms

Facebook X LinkedIn Email
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 at ALS beamline 9.0.1) was of Leonardo da Vinci’s “Vitruvian Man.” This lithographic reproduction of...Read full article

    astronomy
    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    free-electron laser
    A free-electron laser (FEL) is a type of laser that generates coherent, high-intensity electromagnetic radiation by using a beam of accelerated electrons as the lasing medium. Unlike traditional lasers that use atoms or molecules as the active medium, free-electron lasers exploit the unique properties of free electrons, allowing them to produce laser light across a wide range of wavelengths, including the infrared, visible, and ultraviolet regions of the electromagnetic spectrum. Key points...
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
