PLATON detector tracks invisible particles in 3D using AI and a single light block

Scientists have built a particle detector called PLATON that replaces millions of tiny components with a single block of light-producing material. Using a light-field camera, highly sensitive photon sensors and AI, it reconstructs particle paths in fast, detailed 3D. Simulations suggest it could match or surpass today's best detectors, and the technology may also lead to sharper PET medical scans.
