The use of high-speed cameras allows detailed analysis of various phenomena at short time scales. The high-speed camera shown above is equipped with a CMOS sensor, and can record at speeds of up to 6,600 fps (Dt = 151.5 μs) at a resolution of 4 Mpx. These cameras can be used for time-resolved PIV, shadowgraphy, and high-speed Schlieren techniques in fluid engineering research.
The first example on the left shows shadowgraphy of two different liquid droplets falling at high speed through air. The change in the shape of the drop can be clearly observed for one of droplets. The second example on the right shows the change in particle dispersion due to a shock wave generated by laser-induced plasma recorded by high-speed camera.
