“Sonic Boom” Wakes in Spacetime from Light
The researchers out of Washington University's Optical Imaging Laboratory call this a "photonic Mach cone."
To capture video of these elusive light-scattering events, the researchers developed a "streak camera" that could capture images at speeds of 100 billion frames per second in a single exposure. This new camera captured three different views of the phenomenon: one that acquired a direct image of the scene, and two that recorded temporal information of the events so that the scientists could reconstruct what happened frame by frame.
This represents a breakthrough in high-speed imaging, as well as capturing the phenomenon of light traveling at different speeds through different media. The research team is hoping to apply this knowledge to high-speed imaging of electromagnetic pulses in the brain.
