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 ...

Researchers have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system without lenses. The new camera can capture extremely clear pictures over a ...

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, ...
