Researchers have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system ...

A lens-free system produces sharp mid-infrared images even in low light and over long distances, creating new opportunities for improved night vision, industrial inspections, and environmental ...

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

Long before modern photography, the idea of capturing images through a tiny hole fascinated early thinkers. The ancient ...

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 ...

Researchers at East China Normal University have created a mid-infra-red camera with a deep depth of field by creating a virtual pin-hole in an optically-active crystal. The lens-free system not only ...

India is a land of incredible temples, and each has its own unique story, architecture, and cultural importance. Some temples are known for their sheer size and grandeur, while others fascinate ...
