Scientists in China have managed to produce an ultra-fast camera, capable of producing shots with dozens of frames, each taken at a jaw-dropping high speed of a trillion frames per second.
The result might be the most effective slow-motion camera till date.
These high-speed cameras usually capture frames on semiconductors that make up the light sensors, with each frame stored on a separate area of the sensor. But because of how small these sensors are, that means just a few shots available in the output.
However, Feng Chen of Xi'an Jiaotong University in Shaanxi and Lidai Wang at the City University of Hong Kong, had a different idea. With their colleagues, they instead exposed each frame on separate but overlapping areas of the camera sensor, while also tagging each of these frames. The end result is that they can then separate these frames later, giving them a camera that can capture up to 60 shots at 4 trillion frames per second.
With this, the scientists can even capture light in slow-motion as it travels through a material.

This could have a variety of uses in experiments, be it in optical-based communication or physics research. They aso imagine it can be used to watch how human tissue responds to light in laser surgery, all in slow motion. And that might be just the tip of the iceberg.
