A solar eclipse is a rare and spectacular celestial event. It happens when the Sun, Moon, and Earth align so that the Moon passes between the Sun and our home planet, blocking some or all of the Sun's ...
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 ...
A lens-free system produces sharp mid-infrared images even in low light and over long distances, creating new opportunities ...
To prevent damage to your eyes, meteorologist Sean Sublette shows you how to quickly build a pinhole camera — to safely view a solar eclipse.
Long before modern photography, the idea of capturing images through a tiny hole fascinated early thinkers. The ancient ...
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 ...
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 ...
