Researchers test first 'smart spaces' using light to send data

One of the problems in the high-tech field of visible light communication (VLC) - or using light to send data wirelessly - is decidedly low tech: The data transmission stops whenever the light is blocked by people's movements, ...

Analyzing gold and steel – rapidly and precisely

Optical emission spectrometers are widely used in the steel industry but the instruments currently employed are relatively large and bulky. A novel sensor makes it possible to significantly reduce their size and, moreover, ...

Getting the right spin

Rotary sensors can help determine the position of a moveable body in relation to an axis. They are essential to the smooth running of car engines in the automotive industry, for example. Fraunhofer researchers have developed ...

NRL develops low cost, high efficiency solar sensor

Research scientists at the U.S. Naval Research Laboratory (NRL) Electronics Science and Technology Division have developed a novel low cost, highly efficient spectral sensor for field analysis of solar cell irradiance performance ...
