'Sonic Booms' of light captured on camera


Still Waters

Recommended Posts

Just as aircraft flying at supersonic speeds create cone-shaped sonic booms, pulses of light can leave behind cone-shaped wakes of light. Now, a superfast camera has captured the first-ever video of these events.

The new technology used to make this discovery could one day allow scientists to help watch neurons fire and image live activity in the brain, researchers say.

Super cool. The scattering light passes into the nearby material and slows down just a little, causing the cone effect as the main light burst keeps traveling.

I wonder if eventually they'll be able to use such technology to capture a photo of a single photon?
