Ancient 4th-century pinhole concept reimagined in lens-free infrared camera design
A laser-driven “optical pinhole” unlocks distortion-free mid-infrared imaging for night vision and environmental monitoring.
A lens-free system produces sharp mid-infrared images even in low light and over long distances, creating new opportunities for improved night vision, industrial inspections, and environmental ...
A new lens-free system delivers clear mid-infrared images in low light and across long distances. The development offers a ...
Researchers at East China Normal University have created a mid-infra-red camera with a deep depth of field by creating a virtual pin-hole in an optically-active crystal. The lens-free system not only ...
