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 ...

Some security cameras are equipped with a night vision function that uses infrared rays, and the camera can clearly capture the face of a person in the dark where there is no light. Mark Pearce, who ...

Ricoh Co has released the IR (infrared range) camera PENTAX 645D IR. This camera can capture infrared thanks to the placement of a visible light cut filter on the lens. An invisible drawing in a lower ...

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 ...
