Method Images the Invisible

Facebook X LinkedIn Email
RESEARCH TRIANGLE PARK, N.C., March 5, 2009 – Just as x-ray technology, MRI and sonography transformed the practice of medicine, a newly created approach for seeing the invisible promises great potential for finding new ways to improve the health of human and microelectronic patients alike. Semiconductor Research Corp. (SRC), a university-research consortium for semiconductors and related technologies, partnered with Northwestern University to successfully demonstrate a unique ultrasound holography approach that enables scientists to view the tiniest of buried structures. New subsurface, embedded defect analysis will be more...Read full article

    holography
    Holography is a technique used to capture and reconstruct three-dimensional images using the principles of interference and diffraction of light. Unlike conventional photography, which records only the intensity of light, holography records both the intensity and phase information of light waves scattered from an object. This allows the faithful reproduction of the object's three-dimensional structure, including its depth, shape, and texture. The process of holography typically involves the...
    metrology
    Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
    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...
