Scientists reveal ultra-fast photography technique that can capture events up to 100 billion frames per second.
A team of biomedical engineers at Washington University in St. Louis, led by Lihong Wang, PhD, the Gene K. Beare Distinguished Professor of Biomedical Engineering, have made movies of the images they took with single laser shots of four physical phenomena:
Laser pulse reflection, refraction, faster-than light propagation of what is called non-information, and photon racing in two media.
The new technique could be used in medical imaging and to analyse crime scenes.
“For the first time, humans can see light pulses on the fly. Because this technique advances the imaging frame rate by orders of magnitude, we now enter a new regime to open up new visions. Each new technique, especially one of a quantum leap forward, is always followed a number of new discoveries. It’s our hope that CUP will enable new discoveries in science — ones that we can’t even anticipate yet.”
This camera doesn’t look like a Kodak. It is a series of devices working with ‘high-powered microscopes and telescopes to capture dynamic natural and physical phenomena.’
The acquired raw data are actual images formed on a personal computer. The technology is known as computational imaging.
