In this article, we survey various non-contact, non-destructive testing methods by way of
terahertz (THz) spectroscopy and imaging designed for use in various industrial sectors. A …

Six years after their birth, terahertz quantum-cascade lasers can now deliver milliwatts or
more of continuous-wave coherent radiation throughout the terahertz range—the spectral …

Over the past 5 years, there has been a significant interest in employing terahertz (THz)
technology, spectroscopy and imaging for security applications. There are three prime …

Within the last several years, the field of terahertz science and technology has changed
dramatically. Many new advances in the technology for generation, manipulation, and …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

As the volume of composite parts continues to rise, quality and performance specifications
are becoming more and more demanding. In this context, robust and reliable nondestructive …

Real-time, continuous-wave terahertz imaging is demonstrated with a 10? mW, 2.52? THz
(118.8?? m) far-infrared gas laser and a 160× 120 element microbolometer camera. The …

This paper presents a survey of the status of five active THz imaging modalities which we
have developed and investigated during the last few years with the goal to explore their …

THz spectroscopy is advantageous in analytical chemistry because it can detect and identify
intermolecular interactions in chemical compounds, such as hydrogen bonds and …

In the past few years, great effort has been devoted to the fabrication of highly efficient,
broadband radome and stealth (R&S) structures for distinct control, guidance, surveillance …
