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 ...

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 ...

The groundbreaking infrared sensors use layers of repeating molecular structures to interact with individual photons, or units of light. The sensors resolve more wavelengths of infrared at a higher ...

A carbon nanotube transistor turns invisible 940 nm light into both a signal and memory, advancing low-power neuromorphic ...

Over 500 million years of evolution, arthropods have developed complex compound eyes with special visual capabilities 1. In nature, common dragonflies, fruit flies, ants, beetles, and bees have a pair ...

Researchers have developed a tiny chip that could help cameras and sensors see details that are normally invisible to both ...

Researchers have developed a tiny, electrically tunable infrared filter that could help shrink bulky thermal sensing systems ...

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 ...
