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 ...

Records of the natural optical phenomenon of the “camera obscura” pinhole image date back as far as 500 B.C.E. Between the 16th and 19th centuries, it was commonly used as a drawing aid. Artists would ...

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 ...

Pinhole photography is an analog technique that uses a small aperture — a "pinhole" — and a light proof container to capture wonderfully dreamy-looking images. April 26 is Worldwide Pinhole ...

The camera market is filled with materials from plastic to magnesium alloy but the Ondu III is made (mostly) from wood. Returning after two successful Kickstarters, Ondu is back with a new series of ...

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 ...
