  1. High-Speed Imaging Techniques For The Aerospace Industry

    For many years high-speed imaging has been used in various applications by engineers in the aerospace industry. Three very common imaging techniques utilized by these engineers are Digital Image Correlation, Particle Image Velocimetry, and Schlieren Imaging. These imaging techniques provide engineers with great insight into various aspects of the strength and durability of materials, the characteristics of engine combustion processes, the aerodynamics of objects in flight, and much more.

  2. Choosing High-Speed Cameras For Aerospace Testing

    For years high-speed imaging has provided engineers with detailed analysis of projective tracking, missile launches, combustion testing, engine testing, fuselage testing, component testing, materials testing, flow visualization and more. 

  3. How To Choose The Right Camera For Your Automotive Application

    Automotive engineers are continually faced with new vehicle safety requirements and highway emissions standards. The auto industry therefore requires advanced imaging systems to analyze video of everything from onboard and offboard vehicle safety tests to static airbag deployments.

  4. Virtual Engineering Lab Using Photron High-Speed Cameras For Aviation Research

    Wichita State University’s National Institute for Aviation Research (NIAR) is using high-speed digital cameras, manufactured by Photron, in their Virtual Engineering Laboratory in a variety of testing modes such as high-impact dynamic events.

  5. Factors To Consider When Purchasing A High-Speed Video Camera

    There are many factors that are important to consider when you purchase a high-speed camera. Photron USA, Inc. discusses the important factors involved in selecting the appropriate high-speed video camera for your specific information.

  6. Understanding The Dynamics Of Droplets And Turbulence

    Turbulent flows laced with particles can be found everywhere, and include fuel droplets in combustion engines, airborne pollen, and water droplets in clouds. Even though they have been studied often, questions still remain that have to do with the particles’ inertia prohibiting them from following turbulence flow, making the Navier-Stokes equations insufficient for solving their equations. This white paper presents a project studying the dynamics of inertial droplets in a turbulent flow in a well-controlled environment. Measurements of droplet size distribution and turbulent dispersion rate in this study are done with interferometric particle imaging (IPI) and phosphorescent tagging techniques.

  7. Precision Of FLEET Velocimetry Using High-Speed CMOS Camera Systems

    Femtosecond laser electronic excitation tagging (FLEET) is an optical measurement technique that permits quantitative velocimetry of unseeded air or nitrogen using a single laser and a single camera. This paper seeks to determine the fundamental precision of the FLEET technique.

  8. Development Of Background-Oriented Schlieren For NASA Langley Research Center Ground Test Facilities

    This paper provides an overview of recent wind tunnel tests performed at the NASA Langley Research Center where the Background-Oriented Schlieren (BOS) technique was used to provide information pertaining to flow-field density disturbances. The facilities where the BOS technique was applied included the National Transonic Facility (NTF), Transonic Dynamics Tunnel (TDT), 31-Inch Mach 10 Air Tunnel, 15-Inch Mach 6 High-Temperature Air Tunnel, Rotor Test Cell at the 14×22 Subsonic Tunnel, and a 13-Inch Low-Speed Tunnel.

  9. Laser Illumination For High-Speed Imaging

    An incorrect or poorly lit subject affects the image, regardless of camera system quality. Therefore, the illumination source is just as important as the camera's resolution and sensitivity. See how a laser can be used for illumination in these four high-speed imaging application examples.

  10. Using A Photron FASTCAM Camera For Particle Imaging Velocimetry (PIV)

    Particle imaging velocimetry (PIV) can be extremely useful for the analysis of turbulent flow, transient flow, micro flow, and 3D volumetric flow studies within automotive, aerospace, bio-tech/medical, marine propulsion, electronics, and scientific research industries.
