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

    Although schlieren imaging - a noninvasive testing method - can 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.

  2. 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.

  3. 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.

  4. Tradeoffs In High Speed Camera Sensor Design
    4/12/2017

    Jay Stepleton with Vision Research spent a few minutes with us to talk about the tradeoffs involved in speed, resolution, and sensitivity when designing high speed camera sensors.

  5. Three Things To Consider Before Purchasing A High Speed Camera
    2/2/2017

    At Photonics West 2017, Gene Nepomuceno with Vision Research spent a few minutes with us discussing the three main factors one should take into account before selecting a high speed camera – resolution, frame rate, and sensitivity (with an honorable mention for transferring the data off of the camera).

  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.
