  1. Capturing Fast-Moving Ferrofluids On The Nanoscale
    1/26/2018

    When you pass a magnet over the surface of ferrofluids, it begins to reach out with its gooey, spikey arms. A team of researchers at Juniata College is using a Phantom high-speed camera to study its unique, magnetic particles that have vast implications for future lab-on-a-chip devices. The camera helps them to see these too-small, too-fast reactions and capture their nanoscale behaviors.

  2. Optimizing Workflow For High-Speed Imaging Applications
    1/23/2018

    Today’s advanced high-speed cameras are used to record phenomena that are otherwise not visible to the naked eye by capturing the details of fast-moving events. While the images can be incredible, the high frame rates and pixel resolutions used can generate extreme amounts of data in a short period of time. This makes it imperative to optimize the high-speed imaging workflow for the application at hand. Whether imaging in a laboratory, outdoors, or on a movie set, planning an efficient workflow is vital to achieving the best results.

  3. High-Speed Imaging Uncovers The Invisible With Schlieren Techniques
    10/2/2017

    Scientists use schlieren imaging, a noninvasive testing method, to visualize density gradients within otherwise invisible flows. Although this advanced imaging technique can now deliver detailed images of highly dynamic processes, obtaining high-quality data requires choosing the best high-speed camera for the application and careful optimization of the optical setup.

  4. Precision Explosives Analysis Using High-Speed Imaging
    8/24/2017

    High-speed imaging can be used to quantitatively capture explosions, the resulting damage, and to measure other important parameters of the explosion. The data collected can aid in the understanding and characterization of a detonation.

  5. When Lightning And Rods Connect
    8/14/2017

    Marcelo Saba is a modern-day Doc Brown–except that instead of capturing lightning to power a DeLorean time machine in Back to the Future, Saba captures lightning with high-speed cameras to not only advance the understanding of how lightning connects with lightning rods, but also provide the field data necessary to improve current lightning protection systems.

  6. Outcomes Of Mid-Air Collisions Between Drops And Solid Particles
    1/19/2017

    The study of drop-particle collisions involves examining the outcome of the impact of a particle on to a drop of liquid in mid-air. In applications such as tablet coating in the pharmaceutical industry, or the refining of heavy crude oil in fluid catalytic cracking, the information gleaned from this experiment is vital.

  7. The Heat Is On: Examining Two-Phase Flow And Heat Transfer With High-Speed Cameras
    1/19/2017

    We rely on air conditioning and refrigeration to operate through a heat exchanger — a transfer of heat between one or more fluids, essentially increasing heating and cooling efficiency and flow. A group of Pennsylvania State University students is studying two-phase flow and heat transfer phenomena in an effort to advance these processes and their technologies. 

  8. High-Speed Cameras Help Digital Image Correlation Show Its Strength
    12/12/2016

    Digital image correlation (DIC) is an optical measurement technique that allows full-field analysis of a material’s or structure’s deformation, displacement, and strain. This paper discusses how high-speed cameras and various software packages are helping DIC expand into new applications.

  9. Mach Diamonds: Winner Of “Excellent Slow Motion” Award
    12/8/2016

    Mach disks, or “shock diamonds,” are the result of standing shockwaves caused by abrupt pressure changes, usually only seen in the under expanded flow of gas from a jet engine. As the winner of the “Excellent Slow Motion Award” at ICHSIP 31 in Osaka, Japan, this video sequence shows the liftoff of a pressurized PET drink bottle from a toy rocket captured with a Phantom Camera at 50,000 fps, and slowed for viewing by factor of 2,000.

  10. High-Speed Cameras Make Sound Visible And Improve Noise Absorbers
    11/22/2016

    It is extremely important for the airline industry and its research groups to support and develop noise reduction strategies. In this case study high-speed cameras are used to make sound "visible" to researchers while they investigate new strategies for noise reduction on jet engines.
