A lens-free system produces sharp mid-infrared images even in low light and over long distances, creating new opportunities ...
Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors ...
You don’t always need a lens to see a picture, you can use a pinhole camera instead. A pinhole camera uses a small hole that allows light to pass through to allow your eye to see an image. This was ...
Researchers have developed the centuries-old idea of pinhole imaging with a modern twist to create a high-performance system for converting middle-infrared light into visible light, all ...
