You must have watched videos of a bullet smashing an Apple , piercing steel blocks. We’ll talk about how systems that can take videos and pictures of objects moving so fast work, and in addition, systems that are fast enough to shoot even light.
While today’s technology can record images up to a million fps, a new technology called “femto = 101⁵ (quadrillion)”, “femto photography” has emerged in recent years. Thanks to this technology, humanity can now record images faster than light. In this way, the wave behavior of light can be observed and new devices are designed that can even see behind the wall.
The MIT video image explaining the whole process can be found below.
