Screens that can simultaneously work as a Camera are now potentially possible

A camera is a camera and a screen is a screen, till recently they couldn’t be both simultaneously. But last month researchers from ETH Zurich in Switzerland, have created a new type of pixel that can do both at the same time. This hypercharged pixel, called a Fourier pixel, can generate and sense arbitrary light fields and tap into a pixel’s full potential for carrying information by manipulating light’s intensity, oscillation phases, and polarization. Meaning it can display an image and act as a camera at the same time. The paper on the team’s findings was published in Nature. This technology when matured could pave the way for camera–display devices that both display images and act as a camera. One interesting use case would be full functional invisibility. For years we have seen invisibility cloaks, invisible cars and cloaking tech on the movie/TV screens, but most efforts to recreate them have not been successful so far. With this new technology it might soon be possible to have…
