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 ...

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 ...

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 pinhole camera is a simple, safe and free solution that will allow you to watch a solar eclipse — and all you need are a few basic household supplies A pinhole camera is a simple, safe and free ...

In a perfect world, humans would have been able to enjoy the beauty of solar eclipses by looking at them directly. In reality, however, that isn't quite possible, given that looking at the sun during ...

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 ...
