Usually, the high-speed cameras in the hands of sports reporters can clear the records at the speed of 120fps ~ 240fps. What we want to see is the moment when David Becks shoots, the moment when Liu Xiang hurdles and so on. But if you want to see the light, you need faster industrial high-speed cameras.
Researchers at Washington University in St. Louis can track light travel, and a technology called compressed ultrafast photography has been applied. 100 billion frames per second can break the Guinness record. Due to the limitation of on-board storage and electronic readout speed, the maximum speed of only receiving camera is 10 million frames per second.
The picture shows the light travel between a laser pulse and a mirror. We can clearly see the light travel, which is very useful in industry.
