Man has shown considerable ingenuity in seeking out renewable energy – chasing after wind, tides, biomass, sunshine and more. But there is one source that we have not yet tapped – the 10 17 W of ...

Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ...

Efficient light-to-electricity conversion is crucial in applications such as imaging, free-space communication, biological sensing, and clean energy. The bulk photovoltaic effect (BPVE) has garnered ...

Researchers in the US have developed a prototype retinal implant that they hope will help to restore sight to patients blinded by the loss of light-detection cells in their eyes. Although it is not ...

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision ...

(Nanowerk Spotlight) Blackbody response is an important parameter reflecting the sensitivity of infrared photodetectors and determines the corresponding practical applications. It has been widely ...

Speaker one Minus 273 degrees Celsius is the lowest possible temperature. It’s called absolute zero. Any object with a temperature above this will emit and absorb infrared radiation, even the Earth.

This is the fifth article in a series. The advent of stealth aircraft has driven nations East and West to pursue a number of counterstealth technologies. One approach has been to go lower in the ...
