Light Converted To Sound For Weapons Detection, Medical Imaging
2014-05-20 03:22:07

Nicole Casal Moore, University of Michigan A device that essentially listens for light waves could help open up the last frontier of the electromagnetic spectrum—the terahertz range. So-called T-rays, which are light waves too long for human eyes to see, could help airport security guards find chemical and other weapons. They might let doctors image body tissues with less damage to healthy areas. And they could give astronomers new tools to study planets in other solar systems. Those...

Peacock Feathers Inspire Next-Gen Displays
2013-02-06 07:32:03

April Flowers for redOrbit.com - Your Universe Online Peacock feathers have a beautiful iridescence about them — a sheen that shifts colors depending on your perspective. Nature created this color shifting with relative ease, it seems, but it has been a nuisance for engineers trying to reproduce this unique color mechanism to make high-resolution, reflective color display screens. A new study from the University of Michigan reveals researchers have found a way to lock in so-called...

In a step toward more efficient, smaller and higher-definition display screens, a University of Michigan professor has developed a new type of color filter made of nano-thin sheets of metal with precisely spaced gratings. The gratings, sliced into metal-dielectric-metal stacks, act as resonators. They trap and transmit light of a particular color, or wavelength, said Jay Guo, an associate professor in the Department of Electrical Engineering and Computer Science. A dielectric is a material...
