A Video Screen That Is Also a Camera

Researchers from ETH Zurich created a new pixel called a Fourier pixel that can simultaneously generate and sense light fields, potentially leading to advanced display and surveillance technologies. This technology could be used to create devices that can both display video and capture images, similar to the concept of a telescreen from George Orwell's 1984. This development has significant implications for the future of display technology and surveillance systems. The researchers published their findings in a paper in Nature. The potential applications of this technology are vast and could revolutionize various industries.
