The scientists have discovered that light can generate its own cone-shaped wakes, such as sonic boom. But, how can you capture something happening too fast? Actually, you can do it with a very fast camera. These photonic shockwaves using a “Streak Camera” have been recorded by the scientists at the Washington University in St. Louis. They measured both the temporal data and image at 100 billion frames/ second. The team of researchers shot very fast green laser pulses to visualize the cones. It was just 7 picoseconds of duration and a tunnel with full of dry fog was used and placed between plates. These plates were made from silicone rubber and aluminum oxide.
The laser travelled faster in the tunnel instead of plates and it generated a sonic boom-like effect as some of the light bummed out behind. The approach to a very fast camera was actually an important factor. Capturing too fast events using other techniques often need an extra-amount of exposures to see anything, but the streak camera needs just one. It would enable you to capture events that are considered unique and happens just once. It could give new visions into light, but scientists are eventually interested in biology. Their system has been considered too fast to track neurons as they fire, and map the activity of brain in a real time. You may also track a short amount of details, it would improve your understanding of both brain and mind related various types of diseases.
