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 have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system without lenses. The new camera can capture extremely clear pictures over a ...
