Forensic and homeland security applications of modern portable Raman spectroscopy.
Modern detection and identification of chemical and biological hazards within the forensic and homeland security contexts may well require conducting the analysis in field while adapting a non-contact approach to the hazard. Technological achievements on both surface and resonance enhancement Raman scattering re-developed Raman spectroscopy to become the most adaptable spectroscopy technique fo...
متن کاملRaman Spectroscopy for Homeland Defense Applications
Analytical technologies are currently in demand for Homeland Defense applications. Domestic preparedness requires a wide array of detection capabilities for a range of potential attack scenarios. For example, a single location could be attacked by planting an explosives package, carrying an explosive on a person, releasing a chemical/bacterial dispersion into the air supply, releasing a chemica...
متن کاملSensor Placement for Urban Homeland Security Applications
We simulated a sensor network that detects and tracks the release of harmful airborne contaminants in an urban environment. The simulation determines sensor placement in that environment. The effort required integration of models from computational fluid dynamics (CFDs), combinatorial optimization, and population mobility dynamics. These CFD models, coupled with population mobility models, faci...
متن کاملAnimal eyes for military and homeland security applications
While cameras, telescopes, microscopes and other imaging sensors are all instruments supporting the human eye, biologicallyinspired optical imaging systems are becoming increasingly attractive for military and homeland security applications.1 Since the development of classical optical systems, such as the Maxwell fish-eye2 and the Luneburg lens,3 with features reminiscent of fish eyes, other an...
متن کاملMembrane inlet mass spectrometry for homeland security and forensic applications.
A man-portable membrane inlet mass spectrometer has been built and tested to detect and monitor characteristic odors emitted from the human body and also from threat substances. In each case, a heated membrane sampling probe was used. During human scent monitoring experiments, data were obtained for inorganic gases and volatile organic compounds emitted from human breath and sweat in a confined...
