  • ICCD and emICCD Cameras: The Basics

    Intensified CCD (ICCD) cameras use a CCD sensor combined with an intensifier. They are optimal for low-light or single photon applications due to the electron multiplying component of the intensifier.

  • Control of Ultrafast Non-Linear Interactions in Materials and Plasmonic Nanostructures

    Research in the lab of Haim Suchowski generally centers around controlling ultrafast optical processes on the nanoscale. One of the labs main projects investigates the non-linear interaction of plasmonic nanostructures with ultrashort laser pulses with temporal width of 6-20fs.

  • Scientific CMOS (sCMOS) Cameras: The Basics

    Complementary metal-oxide-semiconductor (CMOS) sensors are a technology that has been around since the 1990s. Early CMOS cameras were competing with the more mature CCD technology, but over the 1990s and early 2000s CMOS sensor technology improved to the point where CCD technology was overtaken to become the sensor of choice for consumer digital cameras.

  • Measuring Fusion Plasmas Using Spectroscopy

    The fusion diagnostics and control group led by Ted Biewer at Oak Ridge National Laboratory specializes in measuring and monitoring properties of plasmas in fusion experiments. We talked to Drew Elliott, a scientist in the group: “What we do in our group is develop and operate diagnostics to better characterize a lot of these experiments.”

  • Real-Time Imaging of Singlet Oxygen via Microspectroscopy

    Molecular oxygen is one of the most important molecules in maintaining life as well as in mechanisms by which life is extinguished and materials destroyed.

  • Measuring Large Scale Interactions Between Surfaces with nm Precision to Better Understand Geological Formations

    Although we perceive geological processes on macroscopic length scales, the mechanical behavior of geological structures can be significantly influenced by the microscopic mineral structure of rocks as well as the micro-scale interactions at the contacting mineral surfaces. Microscopic and nanoscale spaces between mineral grains often contain fluids and water that can reactively erode or deposit material, e.g. by promoting crystallization processes.

  • Deep Depleted CCD Cameras for Raman Spectroscopy In vivo and Medical Diagnostics

    Raman spectroscopy is an important measurement technique in life sciences and biotechnology, from nanoscale experiments analyzing the structure of single biochemical molecules to detection of disease and monitoring properties of tissue.

  • Introduction to Raman Spectroscopy

    Raman spectroscopy is an optical scattering technique that is widely used for the identification of materials and the characterization of their properties. It is commonly applied in material science, chemistry, physics, life science and medicine, the pharmaceutical and semiconductor industries, process and quality control and forensics.

  • Bose-Einstein Condensate

    BEC can be described as matter created from matter waves. It is formed when a gas composed of specific particles – “bosonic” particles – is cooled very close to absolute zero. At this low temperature, the wavelength of the matter becomes so large that the wave-like atoms oscillate harmoniously and become indistinguishable, thus forming BEC.

  • Putting Doughnuts on the Line

    This video provides an overview of the integration of robotics, multi-dimensional 2D and 3D vision inspection, and software processing that results in minimized costs and maximized production.

  • Introducing TurboDrive

    TurboDrive is a mode of operation used to push past the gigabit Ethernet speed ceiling, allowing a GigE Vision cameras to send pixel information at a rate in excess of 125 MB/s and speeding up line and frame rates beyond the nominal link capacity.

  • Polarization Imaging

    Polarization offers numerous benefits, not only detecting geometry and surface, but measuring physical properties that are not detectable using conventional imaging. In machine vision, it can be used to detect stress, inspect objects, reduce glare from transparent objects, and enhance contrast for objects that are difficult to distinguish otherwise. When combined with phase detection, polarization imaging is much more sensitive than conventional imaging.
