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 ...

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 ...

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, ...

A team of researchers in China has developed a lens-free imaging system that produces sharp mid-infrared images even in low light and across long distances. The breakthrough promises improvements 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 ...
