A team of scientists at Caltech recently developed a camcorder that can record 70 trillion frames per second, completely surpassing the previous world record of 10 trillion frames. per second, also set by Caltech itself.
The new camcorder uses “high-speed compressed spectral imaging” technology, a new version of “high-speed compression imaging” technology used in previous products. The technology, created by scientist Lihong Wang and his colleagues, is capable of emitting high-speed laser pulses to things, which will then be ‘captured’ by the camera sensor.
In the GIF below, we can see the capabilities of this unique recording technology, with the old type of camcorder taking the right image and the new camera capturing the left image. Each laser pulse projected to the words ‘Caltech’ only lasted for 0.0000000000015 seconds.
Doing a short math, the speed of light is 300 billion millimeters per second, with the rotation speed of 70 trillion frames per second, the camera can record 233.3 frames per millimeter of light. bright, impressive!
Probably everyone guesses, high-speed rotation technology won’t be applied in practice because few people have to shoot things that move so fast. Instead, it will be applied to science: spin the nuclear reaction processes that happen in an instant, the decay of atoms or the path of light as the experiment above.
