Researchers revive the pinhole camera for next-gen infrared imaging. A new lens-free system from east_china_normal_university delivers clear mid-infrared images in low light and across long distances, opening possibilities for better night vision, industrial inspection and environmental monitoring. Because it uses simpler optics and standard silicon sensors, it could eventually make infrared imaging systems more affordable, portable and energy efficient.
