Single-Pixel Camera Captures 3D Holograms, Sees Through Barriers
TheWkly Analysis
Cambridge, UK: Scientists have unveiled a single-pixel camera system that can create 3D holographic images—even of objects hidden behind barriers. By projecting thousands of known light patterns onto a scene and measuring one pixel’s intensity, advanced algorithms reconstruct detailed 3D views. Demonstrations showed real-time holographic videos, including imaging through opaque screens and capturing invisible wavelengths. This approach could transform medical imaging, industrial inspections, and even space exploration. Critics note it requires immense computational power to handle the data, but researchers say better hardware is reducing acquisition times.
