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 ...

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

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

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 ...
