Time-gating technique sees through deep tissue, dense fog, and other obstacles

From helping doctors detect cancer to guiding self-driving cars through traffic, many modern imaging systems rely on near-infrared light, producing a crisp picture when visible light would scatter and yield a blurry picture. But near-infrared systems struggle when light passes through materials like deep tissue or dense fog, succumbing to the same scattering effect in which photons deviate from their path. Existing near-infrared imaging systems also rely on specialized detectors made from expens...
