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 ...

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 ...

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 ...

Capturing photos beyond the visible spectrum is challenging and requires special gear, but the creative payoff is worth it. Here are some of my favorite infrared shots and tips to get you started. Our ...
