When you unlock a phone, step into view of a security camera or drive past a license plate reader at night, beams of infrared ...

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 ...

Because those photographs truly can make or break a case, and the better camera you have, the better evidence that it's going ...

High-performance infrared imaging normally requires exotic materials or cryogenic cooling, making it too costly for ...

Researchers use laser light to form a tiny “optical pinhole” inside a nonlinear crystal, which also turns the infrared image into a visible image that a traditional silicon-based camera sensor can ...
