A lens-free system produces sharp mid-infrared images even in low light and over long distances, creating new opportunities ...

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 ...

Pinhole cameras are not new; they have been around since the beginning of photography. The concept was around long before that. The ancient Chinese and Greeks understood the notion of a pinhole device ...

OK, you want to view the Sun or an eclipse, but you don’t have an approved solar filter for your telescope. Maybe you don’t even have a telescope. No problem! I’ll bet you have a cardboard box. That ...

WASHINGTON — With April's total solar eclipse getting closer, now is the time to plan for how you're going to safely watch the celestial spectacle. Hopefully this isn't the first time you're hearing ...

Researchers have developed the centuries-old idea of pinhole imaging with a modern twist to create a high-performance system for converting middle-infrared light into visible light, all ...

A laser-driven “optical pinhole” unlocks distortion-free mid-infrared imaging for night vision and environmental monitoring.
