A demonstration of four-color Schlieren imaging using the Phantom v2640, an olive, and a soap bubble. The camera resolution was 1920 x 1080, frame rate 10,000 - 12,000 fps, exposure time 83-99 microseconds.

Schlieren – a common technique to measure shock waves – reveals otherwise invisible details like changes in air density during a bubble pop. These moments were captured at MIT's annual short course for high-speed imaging. The classes teach useful techniques to anyone responsible for high-speed motion analysis.
