Schlieren and shadowgraph techniques are basic and valuable tools in various scientific
and engineering disciplines. They allow us to see the invisible: the optical inhomogeneities …

The feasibility of using high-power light-emitting diodes (LED) as a light source for high
frame rate schlieren imaging is investigated. Continuous sequences of high-intensity light …

An imaging system for capturing a sequence of images from a target at ultra-high framing
rates is disclosed. The imaging system includes an illumination system operable to emit at …

A new method to measure shock wave unsteadiness is presented. Time-resolved
visualizations of the flow field under investigation are obtained using a high-speed schlieren …

Multi-channel gated-intensified cameras are commonly used for capturing images at ultra-
high frame rates. The use of image intensifiers reduces the image resolution and increases …

Essentially all processes in gasdynamics are invisible to the naked eye as they occur in a
transparent medium. The task to observe them is further complicated by the fact that most of …

A new ultra-fast camera system is used to study the time evolution of jets in supersonic
crossflows via schlieren imaging. The commercial high-speed camera includes eight …

High-resolution imaging devices are of interest in the development of accurate 3D vision
systems. However, it is challenging to achieve a balance between the image capturing …

High-speed optical shadowgraphy plays an important role in study of various phenomena
including projectile-target interaction for small caliber projectile. Present work reports …
