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 ...

This DIY projector might be the easiest you ever build. By Sandra Gutierrez G. Updated Apr 5, 2024 3:46 PM EDT We may earn revenue from the products available on this ...

Claire Gillo shares her top tips for re-creating a pinhole camera and how to develop your own film. A pinhole camera is simply a box or container that uses a literal pinhole for an aperture. Light ...

You don’t always need a lens to see a picture, you can use a pinhole camera instead. A pinhole camera uses a small hole that allows light to pass through to allow your eye to see an image. This was ...

If you can't get your hands on a pair of solar eclipse glasses, experts say there are still ways to enjoy the event safely. There are also unsafe alternatives, including wearing your normal sunglasses ...

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 ...

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 ...
