Basque Research There are objects we cannot see within the range of the visible but which we can with imaging systems that use the terahertz (THz) wavelength. Within this range we can detect, for example, not only a foreign body hidden under clothing, but also determine what material it is made of. David Etayo, a telecommunications engineer and PhD holder of the NUP/UPNA-Public University of Navarre, has been able to identify explosive components not only in their pure state, but also, and...

IRMMW-THz 2013 attendees are invited to see a demonstration of Lake Shore's prototype terahertz materials characterization system at booth 16. Columbus, OH (PRWEB) August 29, 2013 Lake Shore Cryotronics will be demonstrating software for its prototype terahertz (THz) materials characterization system at the upcoming International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz), September 1-6 in Mainz, Germany. The demo, which can be seen at booth 16 in the Congress...

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...

Helmholtz Association of German Research Centres In their latest experiment, Prof. Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter at the Hamburg-based Center for Free-Electron Laser Science (CFEL) and Dr. Michael Gensch from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) investigated together with other colleagues from the HZDR, the United Kingdom, and Japan if and how superconductivity can be systematically controlled. The objective of their...

Findings point to advances in transistor and solar cell development Researchers at Kyoto University have announced a breakthrough with broad implications for semiconductor-based devices. The findings, announced in the December 20 issue of the journal Nature Communications, may lead to the development of ultra-high-speed transistors and high-efficiency photovoltaic cells. Working with standard semiconductor material (gallium arsenide, GaAs), the team observed that exposing the sample to...

JILA researchers have developed a laser-based source of terahertz radiation that is unusually efficient and less prone to damage than similar systems. The technology might be useful in applications such as detecting trace gases or imaging weapons in security screening. JILA is a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder. Terahertz radiation"”which falls between the radio and optical bands of the electromagnetic...

Unique THz 'fingerprints' will identify hidden explosives from a distance A major breakthrough in remote wave sensing by a team of Rensselaer Polytechnic Institute researchers opens the way for detecting hidden explosives, chemical, biological agents and illegal drugs from a distance of 20 meters. The new, all-optical system, using terahertz (THz) wave technology, has great potential for homeland security and military uses because it can "see through" clothing and packaging materials and can...

John Federici, a physics professor at NJIT, sees the use of terahertz rays as a critical technology in the defense against suicide bombers and other terrorist activities. Federici and his research team recently described experimental results from a digital video camera invented in their laboratory that uses a terahertz imaging system. One day such a device could be used to scan airport passengers quickly and efficiently. "Video-Rate terahertz Interferometric and Synthetic Aperture Imaging"...

"T-rays" may make X-rays obsolete as a means of detecting bombs on terrorists or illegal drugs on traffickers, among other uses, contends a Texas A&M physicist who is helping lay the theoretic groundwork to make the concept a reality. In addition to being more revealing than X-rays in some situations, T-rays do not have the cumulative possible harmful effects. Alexey Belyanin focuses his research on terahertz, otherwise known as THz or T-rays, which he says is the most under-developed and...

Coherent Inc., a world leader in laser technology with headquarters in the USA, and the PTB have joined their expertise in Terahertz technology Terahertz radiation still lies in a metrological no man's land "“ a metrology gap. The Physikalisch-Technische Bundesanstalt (PTB) can now close this gap. For the first time, a commercial Terahertz laser was traced back to the international system of units (SI) by measuring its output power absolutely. PTB achieved this success with a power...
