Fourier Pixel Lets Screens Double as Cameras
3 min read
Researchers at ETH Zurich have invented a Fourier pixel that can simultaneously control and analyze light. The bidirectional pixel manipulates intensity, oscillation, phase, and polarization of light. The technology could enable screens that both display images and sense incoming light, supporting holographic displays and augmented reality.
