Single Pixel Terahertz Imaging Advanced With Laser Guided Codes

Boston College [ Watch the Video Laser Guided Terahertz Imaging ] The universe is awash in terahertz (THz) waves, as harmless as they are abundant. But unlike other regions of the electromagnetic spectrum, THz has proven to be extremely difficult to manipulate in order to capture novel images of objects and materials with which these light waves interact. Most existing THz imaging devices employ prohibitively expensive technology or require several hours and cumbersome manual...

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...

Scientists have developed a new way to create electromagnetic Terahertz (THz) waves or T-rays - the technology behind full-body security scanners. The researchers behind the study, published recently in the journal Nature Photonics, say their new stronger and more efficient continuous wave T-rays could be used to make better medical scanning gadgets and may one day lead to innovations similar to the 'tricorder' scanner used in Star Trek. In the study, researchers from the Institute of...

Researchers have shown how arrays of tiny "plasmonic nanoantennas" are able to precisely manipulate light in new ways that could make possible a range of optical innovations such as more powerful microscopes, telecommunications and computers. The researchers at Purdue University used the nanoantennas to abruptly change a property of light called its phase. Light is transmitted as waves analogous to waves of water, which have high and low points. The phase defines these high and low points...

You canât find evidence that you canât see. FoxFuryâs new Rook ALS LED kit makes it easier to find forensic evidence and finally settles the debate over best wavelength(s). This portable kit features dual wavelength UV (380 + 395 nm) and Blue (450 + 470 nm) light sources that can be powered with lithium or rechargeable batteries. Vista, CA (PRWEB) August 31, 2011 You canât find evidence that you canât see....

Researchers at Columbia Engineering School have built optical nanostructures that enable them to engineer the index of refraction and fully control light dispersion. They have shown that it is possible for light (electromagnetic waves) to propagate from point A to point B without accumulating any phase, spreading through the artificial medium as if the medium is completely missing in space. This is the first time simultaneous phase and zero-index observations have been made on the chip-scale...

UB researcher explains: 'It's as though I can hold the light in my hand.' An electrical engineer at the University at Buffalo, who previously demonstrated experimentally the "rainbow trapping effect" -- a phenomenon that could boost optical data storage and communications -- is now working to capture all the colors of the rainbow. In a paper published March 29 in the Proceedings of the National Academy of Sciences, Qiaoqiang Gan (pronounced "Chow-Chung" and "Gone"), PhD, an assistant...

By Robert Sanders, UC Berkeley University of California, Berkeley, scientists have found a way to overcome one of the main limitations of ultrasound imaging "“ the poor resolution of the picture. Everyone who has had an ultrasound, including most pregnant women, is familiar with the impressionistic nature of the images. One of the limits to the detail obtainable with sonography is the frequency of the sound. The basic laws of physics dictate that the smallest objects you can "see" are...

While those wonderful light sabers in the Star Wars films remain the figment of George Lucas' fertile imagination, light mills "“ rotary motors driven by light "“ that can power objects thousands of times greater in size are now fact. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory and the University of California (UC) Berkeley have created the first nano-sized light mill motor whose rotational speed and direction can be controlled by...

Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...

Doppler Effect -- The Doppler effect is the apparent change in frequency or wavelength of a wave that is perceived by an observer moving relative to the source of the waves. For waves, such as sound waves, that propagate in a wave medium, the velocity of the observer and the source are reckoned relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from both motion of the source and motion of the observer. Each of these effects is analyzed...

vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
