Frank Ospald,Wissem Zouaghi,Rene Beigang,Carsten Matheis,Joachim Jonuscheit,Benoit Recur,Jean-Paul Guillet,Patrick Mounaix,Wouter Vleugels,Pablo Venegas Bosom,Laura Vega González,Ion López,Rafael Martínez Edo,Yehuda Sternberg,Marijke Vandewal +14 more
TL;DR: In this paper, a mobile time-domain spectroscopy system that operates in reflection geometry was proposed for inspection of composite materials from the aeronautics industry, with the goal of developing a mobile mobile time domain spectroglobalization system.
Journal ArticleDOI
Generation and detection of terahertz radiation up to 4.5 THz by low-temperature grown GaAs photoconductive antennas excited at 1560 nm
TL;DR: In this paper, the dependence of the DC photo current and terahertz peak amplitude on the illumination power is measured and found to follow a superlinear power law proposed for sequential charge carrier excitation via midgap states.
Journal ArticleDOI
Precise Determination of Thicknesses of Multilayer Polyethylene Composite Materials by Terahertz Time-Domain Spectroscopy
Norbert Palka,Soufiene Krimi,Frank Ospald,Frank Ospald,Danuta Miedzińska,Roman Gieleta,Marcin Małek,Rene Beigang +7 more
TL;DR: In this paper, the multilayer structure of an ultra-high molecular weight polyethylene (UHMWPE) composite material was investigated in the terahertz (THz) spectral range by means of time-domain spectroscopy (TDS) technique.
Journal ArticleDOI
3D Non-destructive Imaging of Punctures in Polyethylene Composite Armor by THz Time Domain Spectroscopy
TL;DR: In this article, an ultra-high molecular weight polyethylene composite sample totally punctured by a projectile was examined by THz TDS raster scanning method in reflection configuration.
Proceedings ArticleDOI
