World's fastest camera captures 4.4 trillion frames per second

Taking pictures at a resolution of 450 x 450 pixels, the new image-capturing device is purported to be so fast that it can be used to photograph the conduction of heat, which travels at a speed equivalent to one-sixth the velocity of light.

Developed by researchers at the University of Tokyo and Keio University, the camera is said to use a method called femto-photography to capture images in a single burst without the need for repetitive measurements as used in other types of ultra-high-speed cameras. The team reports that this is achieved by using an ultra-short laser pulse split into a series of discrete separate pulses, each in different spectral bands, which illuminate the target object as successive flashes so that the entire scene may be captured using stroboscopic acquisition.
