Hotter objects typically glow brighter than cooler ones, making them stand out in infrared images. But a newly designed coating bucks the rule that hotter equals brighter. For certain wavelengths of ...

A new adaptive surface hides objects from infrared cameras by switching between two modes that match surrounding temperatures in both hot and cold environments. (Nanowerk Spotlight) Infrared cameras ...

D’oh: simulation of infrared radiation from a heat source being blocked by an object shaped like the head of Homer Simpson (left). The image on the right shows how the proposed cloaking device would ...

Barcodes and QR codes feel like they’re everywhere nowadays, but they don’t have to be. Scientists at MIT have developed an invisible tagging system called BrightMarker, which embeds fluorescent tags ...

Infrared inspections often involve analyzing temperature variations on something extremely small or too far away to see the needed detail with standard lenses. The 25 micron macro lens can identify ...

Thinking of buying an infrared camera for generating thermal images? Don't forget that its optics and software are just as important as its sensor chip, says Christiaan Maras. Infrared thermography - ...
