Continuous wave terahertz frequency spectroscopy and imaging for explosives detection and security screenings
DownloadFall 2011
Continuous-wave terahertz (THz) spectroscopy was performed on high explosive materials using the Firefly-THz optical parametric oscillator (OPO). Cyclotetramethylene-tetranitramine (HMX), cyclotrimethylene-trinitramine (RDX), pentaerythritol-tetranitrate (PETN) and Composition-4 were scanned...

Development of a Mid-infrared Detection System for Real-time Measurements of Gas Phase Benzene, Toluene, Ethylbenzene and Xylenes using a Tunable External Cavity Quantum Cascade Laser
DownloadSpring 2012
The chemical transformation of trace gases, including reactions that result in aerosol particle formation, as well as the composition of the atmosphere deeply influence air quality and Earth's global climate. Use of a simulation chamber to study smog formation is a common method to investigate...
