Getting Sharp Images from Dull Detectors

October 13, 2014 11:28 am | by Joint Quantum Institute | News | Comments

In a new experiment, Migdall and his JQI colleagues perform an experiment using incoherent light where the light is a jumble of waves. They use what Migdall calls “stupid” detectors that, when counting the number of photons in a light pulse, can really only count up to zero, as anything more than zero befuddles these detectors and is considered a number that is known only to be more than zero...

Photos of the Day: Setting a Speed Record for Molecular Fluorescence

October 13, 2014 10:42 am | by Ken Kingery, Duke University | News | Comments

When fluorescent molecules are placed near intensified light, the molecules emit photons at a faster rate through an effect called Purcell enhancement. The researchers found they could achieve a significant speed improvement by placing fluorescent molecules in a gap between the nanocubes and a thin film of gold...

Tailored Flexible Illusion Coatings Hide Objects from Detection

October 13, 2014 10:24 am | by A'ndrea Elyse Messer, Penn State | News | Comments

The researchers take the object they want cloaked and surround it with a spacer, either air or foam. They then apply the ultrathin layer of dielectric with copper patterning designed for the wavelengths they wish to cloak. In this way, antennae and sensors could be made invisible or deceptive to remote inspection...
