Thin layered drawing media probed by THz time-domain spectroscopy
J. Tasseva,J. Tasseva,Andrea Taschin,P. Bartolini,Jana Striova,Raffaella Fontana,Renato Torre +6 more
TL;DR: The results showed that THz time-domain spectroscopy enables the discrimination of various inks on different supports, including the application on paper, together with the proper determination of the absorption coefficients and indices of refraction.

Terahertz pulsed imaging as a new method for investigating the liquid transport kinetics of α-alumina powder compacts
Mohammed Al-Sharabi,Daniel Markl,Daniel Markl,Vincenzino Vivacqua,Prince Bawuah,Natalie Maclean,Marian L. Bentley,Andrew P. E. York,Michele Marigo,Karen Huang,J. Axel Zeitler +10 more
TL;DR: In this paper, the authors used TPI coupled with a newly designed flow cell to quantify the rate of water ingress into α-alumina pellets with a range of different porosities.

All fiber-coupled THz-TDS system with kHz measurement rate based on electronically controlled optical sampling.
Roman J. B. Dietz,Nico Vieweg,Thomas Puppe,Armin Zach,Björn Globisch,Thorsten Göbel,Patrick Leisching,Martin Schell +7 more
TL;DR: A completely fiber-coupled terahertz time-domain spectrometer (TDS) system based on electronically controlled optical sampling with two erbium-doped femtosecond fiber lasers at a central wavelength of 1560 nm is demonstrated.

Nondestructive testing potential evaluation of a terahertz frequency-modulated continuous-wave imager for composite materials inspection
Edison Cristofani,Fabian Friederich,S. Wohnsiedler,Carsten Matheis,Joachim Jonuscheit,Marijke Vandewal,Rene Beigang +6 more
TL;DR: In this article, an automated two-dimensional scanner carrying three sensors partially covering the 70-to 320-GHz band is operated, using two complementary measurement approaches: conventional focused imaging, where focusing lenses are used; and synthetic aperture (SA) or unfocused wide-beam imaging, for which lenses are no longer needed.
Journal ArticleDOI
All-electronic terahertz nanoscopy
Clemens Liewald,Stefan Mastel,Jeffrey L. Hesler,Andreas J. Huber,Rainer Hillenbrand,Fritz Keilmann +5 more
TL;DR: In this article, a laser and cryogen-free microwave-technology-based scattering-type scanning near-field optical microscope powered by an easily aligned free-space beam with a tunable frequency up to 075 GHz was demonstrated.
Journal ArticleDOI
OSCAT: Novel Technique for Time-Resolved Experiments Without Moveable Optical Delay Lines
TL;DR: In this article, the authors present a novel technique for time resolved experiments without any moveable external delay line, which is based on a femtosecond laser with a tunable repetition rate and a passive delay line.

Terahertz Time-Domain Spectroscopy of Gases, Liquids, and Solids
TL;DR: Terahertz time-domain spectroscopy is applied to address a broadband frequency range between 100 GHz and 5 THz with a sub-10 GHz frequency resolution and can be efficiently used in material identification and sensing.
