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 ...

IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

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 ...

The aim was to show how powerful surveillance technology such as face recognition appears when used on individuals controlled ...

A new adaptive surface hides objects from infrared cameras by switching between two modes that match surrounding temperatures in both hot and cold environments. (Nanowerk Spotlight) Infrared cameras ...
