X-Rays Image Fragile Scrolls

Facebook X LinkedIn Email
CARDIFF, Wales, Sept. 20, 2007 -- A machine that can generate light beams a million times brighter than conventional x-rays is being used to reveal the text of ancient documents, such as the Dead Sea Scrolls, considered too brittle to be read without destroying them. The Dead Sea Scrolls are hundreds of ancient parchments first discovered in caves by the Dead Sea in 1947, where they had been hidden in clay pots and undisturbed for centuries. The scrolls contain texts from the Hebrew bible and originated sometime between the second century BC and the first century AD, scholars estimate. Many have been considered too...Read full article

    image
    In optics, an image is the reconstruction of light rays from a source or object when light from that source or object is passed through a system of optics and onto an image forming plane. Light rays passing through an optical system tend to either converge (real image) or diverge (virtual image) to a plane (also called the image plane) in which a visual reproduction of the object is formed. This reconstructed pictorial representation of the object is called an image.
    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...
    synchrotron
    A synchrotron is a type of particle accelerator that uses magnetic fields to steer charged particles, typically electrons or positrons, in a closed, circular or elliptical path. The name synchrotron refers to the synchronization of the accelerating electric field with the increasing particle velocity as they move in a circular path. Synchrotrons are powerful tools used in various scientific and industrial applications, particularly in the generation of intense beams of synchrotron radiation. ...
