Raytheon has demonstrated a new type of infrared camera that ditches the conventional approach of capturing full video frames ...

Contrary to popular belief, most property crimes—including burglaries and package theft—happen during the day, not under cover of darkness. But night still brings unique challenges: fewer people ...

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 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 ...
