A Video Screen That Is Also a Camera
Researchers at ETH Zurich developed a pixel technology called a Fourier pixel that can simultaneously display video and capture images by manipulating light intensity, phase, and polarization. The innovation, published in Nature, enables pixels to function as both emitters and sensors in a single component. This advancement moves toward dual-purpose display and camera systems in a single device.
Why it matters: Security practitioners should monitor this technology's deployment in consumer devices and physical security systems, as simultaneous display-camera pixels could enable covert surveillance in unexpected places without obvious visual indicators.
