A device capable of taking 10 trillion pictures per second has recently been invented. What makes it more impressive is that at this speed, it can even capture light traveling in slow motion.
We are very well know Caltech’s Lihong Wang, the Bren Professor of Medical Engineering and Electrical Engineering, the man behind the development of the world’s fastest camera. A little over a year later, he is again in the news and is now trending after developing an even faster device. The new camera from Wang that can now take up to 1 trillion pictures per second, a new paper published in the journal Science Advances on January 17 reveals. The technology, as Wang calls, is phase-sensitive compressed ultrafast photography (pCUP), which is so fast that it can even capture light in slow motion.
The technology can take a video of transparent objects, which is quite astonishing. Not only this, transitory materials such as shockwaves and possibly even of the signals that travel through neurons can be captured by this device. Wang explains that by combining phase contrast microscopy, this would be the world’s fastest camera, which is a device capable of taking 10 trillion pictures per second. Phase-contrast microscopy was created with the aim of high-speed photography, and it was a success as it allowed better imaging of objects, especially those that are transparent such as cells, which are mostly water.
Lossless encoding compressed ultrafast technology (LLE-CUP), is what Wang calls the source of the fast-imaging portion of the system. This phenomenon is quite different from the techniques previously used, which take a series of images in succession while repeating the events. He describes that the LLE-CUP system works by taking a single shot, and then it captures all the motion it observes until the time to which the shot comes to an end.
The ability to work by taking a single shot is much faster than the one that takes numerous shots. This makes the device eligible for capturing things such as the motion of light etc. Wang also demonstrated the abilities of this new technology with his fellow researchers. They passed a shockwave and a laser pulse traveling through a piece of crystalline material through water, after which they were able to image their spreading.
