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 create transparent silver nanowire electrodes to improve IR cameras, enabling clearer imaging and flexible designs for real-world applications. (Nanowerk News) Infrared imaging helps us ...

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 ...
