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 ...
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 ...
