Beam of darkness makes objects invisible from a distance

A research team from the University of Singapore has developed a device that can make objects invisible by bathing them in a beam of darkness.

The system takes the conventional approach to optics -- which generally aims to make images as sharp and clear as possible -- and turns it completely on its head. Usually imaging systems focus light into a pattern known as a point spreading function, which consists of a spiked central region of high intensity (the main lobe) surrounded by a concentric region of lower intensity light and a higher intensity lobe after this. In order to achieve the best resolution, the central region should be narrowed and intensified, while the outer lobe is supressed. This makes sure that the image is very bright and sharp with well-defined edges.

The researchers' beam can hide macroscopic objects by taking the opposite approach: intensifying the outer lobes suppressing the central region. This means that the central region has a field intensity of light that is pretty much zero.

By some weird coinky-dink, I’m working on light absorbing diodes...

"Bring out yer DED?"

Why do you think they call them Die-odes?

If you want something wonderful, look at some Gee-odes.

Do yourself a favor, though, and stay away from Poetical-odes.

Poetical-odes to someone named edda might get you sent on a Nordic odyssey.

And all this time I thought the only use for a DED (dark emitting diode) was as a power off indicator.

No doubt the pirate Roberts on the subPreme Court will stamp a law called the Affordable Snare Act constitutional so long as it is implemented by little barry basatrd boy-king.
