Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength ...

How does heat energy turn into visible light? As objects grow hotter ... according to NASA's Mission Science. For example, the flame of a blowtorch changes from reddish to blue as it is adjusted ...

It just happens that the light emitted from most objects is not visible to the human eye. Let’s take a look at an example. Here is an ordinary stove top eye. When you first turn it on ...

Chinese researchers have developed an infrared contact lens that makes night vision possible. Nanoparticles make the ...

Here's an example of my dog ... (especially in the 8 to 13 micrometer wavelength). The visible light will reflect off the object so that it doesn’t cause thermal heating, and the infrared ...

The light pulses bounce off objects and back to the sensor, allowing the system to map the 3D environment it's in. But lidar falls short when objects absorb more of that near-infrared light than ...

(See “Cloaking Breakthrough.”) This latest work now shows a way to extend this into the visible-light range, says Pendry. To become invisible, an object must do two things: it has to be able ...

When electromagnetic radiation, including visible light, falls on baryonic objects, they absorb photons and reemit them, or simply reflect them, so these objects can be seen. Even dark clouds of ...

Research published in ACS Applied Materials & Interfaces describes a highly reflective black paint that could help these cars see dark objects and make autonomous driving safer. Lidar, short for light ...
