High-Speed Imaging Uncovers The Invisible With Schlieren Techniques

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.

Precision Explosives Analysis Using High-Speed Imaging

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.

When Lightning And Rods Connect: High Speed Imaging Brings Understanding

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.

High-Speed Cameras Make Sound Visible And Improve Noise Absorbers

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. 

Tradeoffs In High-Speed Camera Sensor Design

Jay Stepleton talks about the tradeoffs involved in speed, resolution, and sensitivity when designing high-speed camera sensors. He also provided a brief history on high-speed imaging, how far its technology has been improved upon over the last decade, and offered some predictions for future developments.
