Journal ArticleDOI
THz spectroscopic investigation of 2,4-dinitrotoluene
Yunqing Chen,Haibo Liu,Y. Deng,Dunja Schauki,Michael J. Fitch,Robert Osiander,Caroline Dodson,James B. Spicer,Michael Shur,Xi-Cheng Zhang +9 more
TL;DR: In this article, the terahertz (THz) spectrum of 2,4-DNT was investigated by using Fourier transform infrared spectroscopy in the 0.2-19.5 THz region.
Journal ArticleDOI
Theoretical noise-limited sensitivity of classical interferometry
James W. Wagner,James B. Spicer +1 more
TL;DR: In this paper, the signal-to-noise ratios for the path-stabilized, active-heterodyne, Sag, and Fabry-Perot interferometers are calculated for cases in which dynamic surface displacements are detected.
Proceedings ArticleDOI
Spectroscopic characterization of explosives in the far-infrared region
Yunqing Chen,Haibo Liu,Y. Deng,Dmitry Veksler,Michael Shur,Xi-Cheng Zhang,Dunja Schauki,Michael J. Fitch,Robert Osiander,Caroline Dodson,James B. Spicer +10 more
TL;DR: In this article, the far infrared spectra of 14 commonly used explosive samples have been measured by using Fourier Transform Infrared Spectroscopy (FTIR) and THz Time Domain Spectrographs (THz TDS).
Journal ArticleDOI
Line source representation for laser-generated ultrasound in aluminum
TL;DR: In this work, a laser line source was modeled and verified experimentally by measuring the ultrasonic shear wave signal generated in aluminum with a broadband laser generation/electromagnetic acoustic transducer (EMAT)-detection system.
Journal ArticleDOI
Femtosecond and nanosecond laser-induced breakdown spectroscopy of trinitrotoluene
TL;DR: Aluminum emission lines from the substrate are also observed with both femtosecond and nanosecond excitation and indicate the role played by the substrate in the interaction, which is dominated by emission from the elemental constituents of the explosive.
