Lensless X-ray Microscope Images Nanoscale Detail

Facebook X LinkedIn Email
SAN DIEGO, Aug. 12, 2011 — A new x-ray microscope that computes images using an algorithm rather than a lens is allowing scientists to see minute details at the nanoscale. The algorithm can convert the diffraction patterns of x-rays bouncing off an object, yielding images with nanoscale detail. The system works somewhat like adaptive optics, making continual calculations to yield a resolvable image. Magnetic domains appear like the repeating swirls of fingerprint ridges. As the spaces between the domains get smaller, computer engineers can store more data. (Image: UC San Diego) To test their microscope's...Read full article

    adaptive optics
    Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effects of atmospheric distortions. The Earth's atmosphere can cause light passing through it to experience distortions, resulting in image blurring and degradation in various optical applications, such as astronomical observations, laser communications, and imaging systems. Adaptive optics systems actively adjust the optical elements in real-time to compensate for these distortions. Key...
    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.
