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 ...

IR cameras are propelling the automotive industry forward with their improved precision and efficiency in manufacturing.

Infrared imaging helps us see things the human eye cannot. The technology—which can make visible body heat, gas leaks or water content, even through smoke or darkness—is used in military surveillance, ...

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 ...
