Compound Explosives Detection and Component Analysis via Terahertz Time-Domain Spectroscopy
We present qualitative and quantitative component analyses on compound explosives via Terahertz time-domain spectroscopy (THz-TDS) based on a combination of wavelet thresholding and wavelength selection. Despite its importance, the field of signal processing of THz signals of compound plastic explosives is relatively unexplored. In this paper, experiment results from explosives Composition B-3 ...
متن کاملWideband terahertz spectroscopy of explosives
Time-domain terahertz spectroscopy (TDTS) has been shown to be a promising tool in detection of explosives and explosive related compounds. To date, TDTS for many explosives has been limited to spectral regions <3 THz. With recent improvements in emitters and sensors of THz radiation, we report the THz absorption spectra over an extended frequency band from 0.5 to 6 THz for four explosives: RDX...
متن کاملTerahertz Spectra of Explosives Measured by Optical Parametric Oscillator-Based System and Time Domain Spectroscopy
In this paper, we report on measurements of absorption spectra of hexogen, penthrite, and octogen. The measurements were carried out by means of time domain spectroscopy and compared to spectra obtained from a setup, which bases on an optical parametric oscillator combined with a Golay cell. For time domain spectroscopy measurement, Teraview TPS 3000 unit with accessories in transmission con gu...
متن کاملTerahertz spectroscopy of explosives and drugs
The electromagnetic spectrum, illustrating the position of the terahertz (THz) frequency range with respect to the neighboring microwave/millimeter and mid-infrared (IR) regions of the spectrum, is shown in Fig. 1. The THz range is conventionally considered to be 0.3–10 THz ≡ 10–300 cm–1 ≡ 1–0.03 mm, although different authors adopt slightly different definitions. There has been considerable in...
متن کاملTemperature-dependent far-infrared spectra of single crystals of high explosives using terahertz time-domain spectroscopy.
Survey spectra of single-crystal HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine), RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine), and PETN (pentaerythritol tetranitrate) were acquired in the region from 10 to 80 cm(-1) using terahertz time-domain spectroscopy. The spectra were taken at temperatures ranging from 8.4 to 300 K. Generally, the spectra show multiple absorption peaks in the ran...
