  1. 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. 

  2. 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.

  3. 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.

  4. 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. 

  5. Explosives Engineering: High Speed Imagery For Research And Experimentation
    11/22/2016

    Vision Research is in collaboration with the Colorado School of Mines in order to develop a university-level short course on the use and benefits of high-speed imaging, while experimenting with explosives and ballistic applications.

  6. Vocal Folds: High-Speed Digital Cameras Facilitate Revolutionary Research In Diagnosing Voice Disorders
    11/22/2016

    Voice disorders are unfortunately not as uncommon as most people would think. Around 7.5 million Americans have trouble using their voice every day, and not enough is known about this subject to understand how to prevent these disorders. Dr. Deliyski, a researcher at the University of South Carolina’s Arnold School of Public Health, is committed to advancing the scientific understanding of the human voice, and plans to develop a new methodology to help diagnose voice disorders. With the help of Vision Research, this study explores the movements of human vocal folds through laryngeal high-speed video-endoscopy (HSV).

  7. High Speed Cameras Aid In Spacecraft And Astronaut Safety For NASA
    11/22/2016

    At a lab in New Mexico, A team is assessing this dangerous “space trash” with the use of ultra-high-speed imaging cameras. They fire fake “space trash” no bigger than a pea at things like oxygen tanks and steel cables. Let’s just say it never ends well (everything gets ripped in half), and the scientists can’t even see the projectiles to track them. That’s where Vision Research Phantom cameras, such as the Phantom v711 and Phantom v2512, come in. With the ability to record this astronomical data, these imaging cameras reveal a new level of understanding of the destruction that something like “trash” can cause to a spacecraft or astronaut.

  8. Advancing Microfluidics Research Using High-Speed Cameras
    9/8/2016

    With a growing field of microfluidic applications, high-speed camera systems are utilized for accurate analysis of the quickly changing micro scale fluid dynamics. This article discusses using high-speed cameras for microfluidic data acquisition.

    This video gallery presents a wide variety of video demonstrations using the high-speed digital cameras from Vision Research for many different markets including ballistics, scientific, industrial, and automotive.

  10. Boosting Sensitivity
    3/29/2016

    When purchasing a camera, especially for “light starved” applications, the correct light sensitivity is an important specification to consider. Light sensitivity is more open to user or vendor manipulation, unlike more unambiguous specifications such as the maximum resolution or frame rates at key resolutions.
