  1. Video Results Of Helmet Without DIC
    12/12/2016

    The video displays a helmet impact at 3,333 fps without digital image correlation (DIC).

  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. A Study In Droplets
    9/22/2016

    This video presents different liquid drops captured at high speeds with the Phantom VEO 640 at 1,500 fps, and the Phantom VEO 710 at 8,000 fps.

  9. 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.

  10. Shadowscopy Technique Part 2
