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 ...

A researcher has developed a new technique to detect long wave infrared (LWIR) photons of different wavelengths or 'colors.' The new detection and imaging technique will have applications in analyzing ...

In the natural world, snakes possess a unique “superpower”. Using specialized “pit organs”, they can detect infrared radiation, generating thermal images of prey even in total darkness. This ...

Snake-inspired thermal vision is moving from the lab toward devices that look a lot like everyday cameras and phones. By mimicking how vipers sense heat and fusing that idea with standard silicon ...

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 ...
